INTRODUCTION

Thank you very much for purchasing iCLOCK or iCLOCK dp, Redundant Multiple Clock Synthesizer & Video Reference Generator, from MUTEC!

About this Manual

The whole manual is related to both versions in general, iCLOCK and iCLOCK dp. The individual differences are mentioned in the according sections and chapters.

The structure of this manual refers to the normal process of installing iCLOCK in a standard audio/video studio environment. Thus the chapters are ergonomically sorted to provide a fast set-up. Before first power-on we recommend to read the chapters INTRODUCTION and BRIEF INSTRUCTIONS to get to know the general functionality of iCLOCK and to reach a fast system integration.

The following chapters OPERATION and iCLOCK TECHNOLOGY describe individual functions which enable the adaption of iCLOCK to every studio environment. The chapters APPLICATION EXAMPLE and APPENDIX include descriptions of favorable studio set-ups as well as all technical information.

If there are any uncertainties when operating the units which can not be cleared up by the content of this manual, please feel free to contact your local dealer or MUTEC directly. All contact details are included in chapter WARRANTY REGULATIONS located at the beginning of the manual.

The grey boxes contain supplementary information for the corresponding sections in the text columns. The content of the individual box refers to the description in the text column beside the box.

Boxes which contain a triangle with an exclamation mark should

be read carefully! These include additional information which are of major importance for the functional descriptions in the text column.

General Function Description

iCLOCK is a synchronizable, high-precision clock generator which is designed to be the reference in digital audio and video studios as well as broadcast and television stations. Based on a totally new concept of frequency generation, developed by MUTEC, the unit offers an unchallanged flexibility for synchronization of different devices to one house clock. On this occasion iCLOCK breaks traditional, unflexible forms of chaining input and output signals and allows for the first time their completely free combination and scaleability.

iCLOCK‘s philosophy is addressed to provide the highest possible failure safety for all outgoing clock signals which is needed especially for broadcast stations or centralized clock distribution systems. With regards to this functionality up to 3 independent external references can be autodetected and locked in a user-defined sequence without any phase-jumps or interruptions in the outgoing signals. This applies also to external clock frequency changes, e.g. from 44.1kHz to 48.0kHz or reference clock changes, e.g. from video to GPS or AES11. Even if all external references are lost, iCLOCK synthesizes the outgoing clock signals based on the last incoming frequency constantly. If the absent reference clock returns the synthesizer will lock gradually again based on iCLOCK’s SoftReLock functionality which ensures interruption-free adjustments of all outgoing clock signals. In this case a continous clock supply for all connected devices is guaranteed during any operation mode.

For todays audio/video productions a precision synchronisation of the used audio and video equipment is imperative. To reach the highest value of accuracy the involved clock signals need to be synchronized and converted without any phase drift. Therefore iCLOCK offers a unique, automatically working signal management which observes the phase relationships of all input and output signals and takes care of adjustments aligned to AES11-1997/2003 and EBU R83-1996.

Using DDS-coupled frequency generation and latest DSP-based filtering technologies in combination with an extremely low-jitter clock basis of < 10ps (RMS), iCLOCK eliminates the jitter of incoming reference signals completely. This ensures highest possible jitter attenuation for all outgoing clock signals. As a result the synchronization of connected devices is much more reliable and the sound quality of every AD/DA converter will be increased significantly.

Differences between Software V2.10 and V2.11

Both versions include the preset management as new functionality, which was inquired by several professonal MUTEC customers (see page 28). Using software V2.10 or V2.11 depends on the alarm interface you have already installed or you plan to install. Software V2.10 supports only the older interface iC-ALARM (ordering no. 8005- 056), whereas software V2.11 supports only the new iC-AL ARM/GPI (ordering no. 8005-066).

The iC-ALARM/GPI interface offers same basis functionality like the iCALARM, but the new iC-ALARM/GPI interface allows for switching over the different presets via its GPIO function (see page 31, 32).

5 PAL/NTSC VIDEO OUT SD bi-level PAL and NTSC composite video sync signals are sent from these outputs. After installing the optional P/NVSG-02 video sync generator (item no. 8010-010), a separate video format can be assigned to each output pair. Associated output pairs are arranged on top of each other. If a HD tri-level sync signal is applied to a reference input, the incoming reference can be distributed through the PAL/NTSC video outputs. The individual BNC terminals of an output pair are marked as A and B; this allows, for example, for a simple documentation of the connected devices.

6 WORD CLOCK OUT

Refer to the »Synchronizable and generatable Clock Rates« section in the APPENDIX for a full list of all Word Clock, AES/EBU and S/P-DIF clock rates that can be generated.

For detailed specifications on all terminals, refer to the »Pin assignment of the Connectors« and »Technical Data« sections in the APPENDIX.

These outputs send Word Clock, Word Clock x 256 signals and film / video frame / field clock rates. Each of the output pairs can be assigned with a separate clock rate. Associated output pairs are arranged on top of each other. The individual BNC terminals of an output pair are marked as A and B; this allows, for example, for a simple documentation of the connected devices.

7 + 8 AES/EBU OUT1, AES/EBU OUT2 These outputs send a balanced digital AES/EBU audio or blank frame signal compliant with AES3 – 1992 (R1997) and AES11 – 1997. Each of the output pairs can be assigned with a separate clock rate, and the channel status bits can be edited individually. The rear-panel outputs are marked as AES OUT 1 and AES OUT 2, the individual output terminals as »A« and »B«; this allows, for example, for a simple documentation of the connected devices.

9 S/P-DIF OUT These outputs send an unbalanced digital S/P-DIF audio or blank frame signal compliant with IEC 60958. The channel status bits can be edited. The individual output terminals are marked as A and B; this allows, for example, for a simple documentation of the connected devices.

10 RS 485 This interface port is provided for programming the iCLOCK and updating the device firmware. A software for remotely controlling the device over LANs (Local-Area Networks) will be available in the future.

INSTALLATION

Content of the Box

The unit was packed carefully. Nevertheless we recommend to check the content directly after opening the package:

1 x iCLOCK / iCLOCK dp 1 x Power cable, 2 x power cables for iCLOCK dp 4 x Rubber feet 1 x Manual 1 x Registration card

Placing the Device

The unit should be set up as closely as possible to the devices to which it will be connected, so as to avoid excessive cable lengths. Use the 4 rubber feets enclosed with the appliance and stick them symmetrically on the bottom side of the unit to protect the enclosure and supporting surface from being damaged.

The device can be mounted into a standard 19“ rack and will require 1 unit. In this case, the rubber feet cannot be attached. Install the device so that one unit of rack space is left free both above and below the device to allow for sufficient ventilation! The mounting depth including the terminals is 240 mm/9.45“ for iCLOCK and 280mm/11.02 for iCLOCK dp. Another 60 mm/2.4“ should be added for the required cables.

Additional slide-in rails on the rack inside are recommended for safe installation. This will also avoid long-term mechanical deformation of the housing.

be checked carefully additionally. If there are any damages please refer to SAFETY INSTRUCTIONS, Initial Operation, and WARRANTY REGULATIONS.

Before installing the unit the section SAFETY INSTRUCTIONS located at the beginning of this manual should be read carefully.

Never expose the device and accessories to rain, moisture, direct sunlight, or excessive heat produced by radiators, heaters, or spot lights! Sufficient air circulation in the environment of the device must be ensured!

Wiring the Word Clock and Video Interfaces

To allow for synchronization of signals, the interfaces of all devices involved must be properly connected to each other, so as to ensure a logical signal flow. Always be sure to connect the Word Clock outputs of iCLOCK to the according inputs of the devices you wish to synchronize! Cable lengths should be kept as short as possible to minimize signal losses and/or interference!

For the transmission of Word Clock or video signals electrical, asymmetrical cables with a resistance of 75Ω and BNC connectors on both ends are used. Typically, such cables are marked »RG-59U, RG59B/U«.

Additionally, you should make sure that the Word Clock or video inputs to be connected to iCLOCK’s outputs have a 75 Ω terminating resistor! Most Word Clock or video inputs allow for enabling/disabling the termination with a so-called »termination-switch«, which may be located on the outside or inside of the device.

For devices which have no termination of the Word Clock input, e.g. RME Hammerfall with Word Clock i/o or Alesis BRC, you can use an additional BNC-T piece to terminate the input. Plug the T piece with its center connector into the input of the receiving device. Then, connect the cable coming from iCLOCK to one of the lateral connectors, and the other connector of the BNC-T piece to a 75Ω resistor forming the BNC termination.

Basically, you should avoid »looping through« Word Clock leads by means of passive BNC-T pieces to preserve the signal quality, as level drops will be the result. If there is no other way to wire your set-up, please make sure that all Word Clock inputs (except for the last device in the chain) have their terminations disabled! In a serial Word Clock chain only the last clock input should have a termination! Never connect more than three devices in series to one output!

Clock Cable Lengths

It is imperative that the lengths of

all cables connected are largely the same, as this is the only way to ensure that all devices will be synchronized in phase (exception: cable tolerances).

Please make sure that the cable used has a resistance of 75 Ω , in compliance with the specifications! If a cable with a different resistance is used, a dramatic deterioration of the signal quality can be the result! In this case, the perfect synchronization of all devices involved could be impaired.

We recommend using high-grade cables with a good shielding for your clock signal leads, in particular, if you need to transmit Word Clock x 256 (so-called Super Clock) signals over greater distances. In any case, a length of max. 10 meters (approx. 30 feet) should never be exceeded!

Wiring the AES/EBU and S/P-DIF interfaces

Cables for High Clock Rates

Especially when working with high

AES3/-11 clock rates well shielded clock lines are imperative to avoid increased radiation! Standard cables are nor-mally useable for clock rates up to 50.0kHz. Special shielded cable material should be used for transfer of higher clock rates.

Since some manufacturers offer optimized cables for the transmission of digital S/P-DIF and AES3/-11 signals, it will be a good idea to ask your retailer for specific cables.

Connect the AES/EBU interfaces with the help of balanced electrical cables equipped with XLR connectors on both ends. The specifications stipulate a specific cable resistance of 110Ω (ask your retailer for a confirmation of this value when purchasing the cables).

Connect the coaxial S/P-DIF interface with the help of unbalanced elec trical cables equipped with cinch connectors on both ends. The specifications stipulate a specific cable resistance of 75Ω (ask your retailer for a confirmation of this value when purchasing the cables).

Menu main page

All user-specific parameter settings are available furthermore when power is restored.

INPUT REF1, -2, -3

INPUT REFERENCE, shows an abbreviation of the clock source currently selected incl. its reference slot and its actual rate as a realtime measurement. As display space is limited, the displayed value is automatically adapted with regard to the decimal places and the frequency unit as follows:

Hz = hertz k = kilohertz M = megahertz

Refer to the »Selecting Clock Sources« section in this chapter for information on individual sources.

STATUS (function)

Shows the current system status. STATUS provides information on the device synchronization and possible system errors. Major functionalities are indicated through eight LEDs on the right hand side of the display additionally.

LOCKED (status message)

LOCKED indicates that the system has synchronized to the internal video reference generator or an externally applied clock signal. At the same time, the blue LOCK indicator associated with the active clock input (INPUT 1 - 3) will light.

FQ CHANGE (status message)

FREQUENCY CHANGE indicates that a sync source change is occurring. This can be a change between two externally applied clock signals or an automatically or manually performed change from an external to an internal clock source (or vice versa). When the change occurs, the LOCK indicator of the last clock source used will go dark, and the red HOLD indicator will light. When the system has locked to the new source, the HOLD indicator will go dark, and the associated LOCK indicator will light.

HOLD (status message)

HOLD indicates that an externally applied clock signal has either drifted outside its permitted lock range (see the PULL RANGE parameter on the GLOBAL 1/4 page) or is completely lost. In this case, the system waits for a certain period for the signal to return before automatically changing to the next clock source. This waiting period specified by the LONEREF parameter on the GLOBAL 2/4 page.

CYCLESYNC (status message)

CYCLE SYNCHRONIZATION indicates that the system is currently performing an automatic resynchronization. This function can be disabled on the REF1–3 page or be enabled manually for individual clock source inputs.

Status Displays

When iCLOCK is running in INTERN

mode the first blue LED, LOCK REF 1, will light and confirm the synchronization of the synthesizer to the internal video reference generator.

After first switching on, the synthesizer needs approx. 30 seconds to achieve stable synchronization. This depends on the time the video reference generator needs for attuning all components of its video output signal.

During this process the system re-locks temporarily (the HOLD LED and the blue LOCKED REF 1 LED are lightening alternately). This has no relevance for system security. The output clocks are constantly available.

Error Messages

If one of the messages OSCI FAIL,

MAIN1LOST or MAIN2LOST is displayed, safe operation is not guaranteed! Contact the technician in charge immediately!

MAIN 1 LOST indicates that the primary supply voltage or the primary internal power supply have failed. If this status message is indicated, contact the technician in charge immediately! The message is displayed only if the iCLOCK is equipped with a redundant power supply (iCLOCK dp version, item no. 8015-046).

MAIN2LOST (status message)

MAIN 2 LOST indicates that the secondary supply voltage or the secondary internal power supply have failed. If this status message is indicated, contact the technician in charge immediately! The message is displayed only if the iCLOCK is equipped with a redundant power supply (iCLOCK dp version, item no. 8015-046).

OUTPUTs (function)

Here, the set clock rates of all outputs are displayed alternately as a »ticker«. This allows for checking the settings directly with no need for changing to the relevant menu pages.

The following clock signals or rates are factory defaults:

PAL/NTSC VIDEO OUT 1 + 2 = PAL Black + Burst WORD CLOCK OUT 1 – 4 = 44,1kHz AES3/-11 OUT 1 + 2 = 44,1kHz S/P-DIF OUT = 44,1kHz

Activating Clock Sources

After selecting a new clock source

under REF1 – 3, it is imperative to move the cursor to the SYNC function and to press ENTER for activating the selected reference for synchronisation!

Setting REF1 – 3

The most important clock source

in your studio environment should always be assigned to REF1! This is critical for proper completion of the CYCLE-SYNC setting. Afterwards, the other REF slots should be assigned with sources in a hierarchical order.

Selecting and activating Clock Sources

The REF1-3 page allows for selecting the clock source of the internal synthesizer. The clock formats supported by iCLOCK are listed in the adjacent table. The factory defaults are REF1 = INTERN, REF2 = NO REF, REF3 = NO REF.

If one of the synchronizable clock sources is selected, the respective signal format is marked with an index (1 + 2) referring to the two universal clocksource inputs INPUT 1 and INPUT 2. Thus, the input clock signals can be routed freely to these two system inputs. The AES format, however, is an exception as balanced AES/EBU signals can be received by INPUT 3 only.

When selecting clock sources, the system proceeds logically. For example, if the PAL1 source (PAL video on INPUT 1) has been selected under REF1, it will not be available anymore for REF2 and REF3. This means that only sources with an index of »2«, »AES«, »INTERN«, and »NO REF« can be configured. Likewise, a clock source programmed for REF2 will not be available for REF3 anymore.

If a clock source is routed to one of the REF slots it has to be activated for synthesizer synchronization. Therefore the last modified REF slot is displayed in the SYNC function menu automatically. Moving the cursor to this position and pressing the ENTER button will activate the synchronization process to the new clock source immediately.

REF1-3 page

REF 1, REF2, REF3 (function)

This function allows for selecting three clock sources supported by the system and for assigning them to a clock source slot. The sources will synchronize the system in their numeric sequence (REF1 → REF2 → REF3).

INTERN (setting)

INTERNAL Selecting the INTERN setting synchronizes the synthesizer to the internal video reference generator that supplies all audio clock signals in compliance with AES11 and EBU R83. As internal synchronization is the ultimately selected source, no other sources will be left afterwards. Therefore, when selecting INTERN for REF1, the REF2 and REF3 functions will automatically be assigned with the »NO REF« setting.

Refer to the »Synchronizable and Generatable Clock Rates« section in the appendix for a full list of all clock rates.

AESid 1, -2 (setting)

AESid1, -2 allows for synchronizing the synthesizer to all audio-related AES3/-11 rates in a range of 32…192kHz. The applied clock rate is recognized automatically. Both AES 3id or AES 11id compliant signals can be applied. In addition, S/PDIF signals can be applied to this input and be used for synchronization. Refer to the »Synchronizable and Generatable Clock Rates« section in the appendix for a full list of all clock rates.

S/P-DIF1, -2 (setting)

S/P-DIF1, -2 allows for synchronizing the synthesizer to all audio-related S/P-DIF rates in a range of 32…192kHz. The applied clock rate is recognized automatically. Both S/P-DIF audio or S/P-DIF blank frame signals can be applied. Refer to the »Synchronizable and Generatable Clock Rates« section in the appendix for a full list of all clock rates.

New References

For special-purpose applications, the range or number of the sync-clock references can be extended by means of a software update. Practically any frequency or frequency range between 1.0 kHz and 30.0 MHz can be defined. The only precondition is that the new clock source can be connected to and processed by the BNC inputs (INPUT 1 and INPUT 2) according to their specifications.

When applying Word Clock, GPS, Telecom, DCF77 or MFS60 sources, both pulse and sine signals will be accepted which allows for processing even heavily slurred signals.

If an option supporting new input clock formats is installed, these will automatically be implemented by the system and will be available for selection on the REF1–3 page.

GPS 1, -2 (setting)

GPS1, -2 allows for synchronizing the synthesizer to all sources with standard GPS rates (1.0MHz, 2.5MHz, 5.0MHz, and 10.0MHz). The actual clock rate will be recognized automatically.

TELEC 1, -2 (setting)

TELECOM1, -2 allows for synchronizing the synthesizer to sources providing the standard Telecom clock rates of 1.024MHz or 2.048MHz. The actual clock rate will be recognized automatically.

DCF 77 1, -2 (setting)

DCF771, -2 allows for synchronizing the synthesizer to sources providing a DCF77 clock rate (77.5kHz). This reference is transmitted from Mainflingen / Germany with a range of approx. 2000kms.

MSF60 1, -2 (setting)

MSF601, -2 allows for synchronizing the synthesizer to sources providing a MSF60 clock rate (60.0kHz). This reference is transmitted from Rugby / UK with a range of approx. 1500kms. From April 1st, 2007, it will be transmitted from Anthorn.

HD-P- 1, -2 (setting)

HD-P-1, -2 allows for synchronizing the synthesizer to HD tri-level sync sources with frame rates of 24Hz, 25Hz, 30Hz, 50Hz, 60Hz.

HD-N- 1, -2 (setting)

HD-N-1, -2 allows for synchronizing the synthesizer to HD tri-level sync sources with frame rates of 23.98Hz, 29.97Hz, 59.94Hz.

NO REF (setting)

Selecting the NO REF setting disables the respective clock-source slot. If, for example, only two clock sources are connected to the device and REF1 and REF2 are configured accordingly, assign the NO REF setting to the REF3 slot in order to disable this slot for the automatic resynchronization function (see also CYCLESYNC).

iCLOCKdp to HD tri-level references, their individual frame rates can not be displayed correctly under »STATUS«, as it is the case when locking SD bi-level references. This is due to system reasons. But your iCLOCK will be locked as it should be.

SYNC (function)

As the synthesizer is capable of continuously supplying the adjusted iCLOCK output signals, even a manual clock source change on an input (by replugging the clock lines) is supported during operation!

It is not important whether the change occurs, for example, from a PAL SD video signal to a Word Clock or GPS signal. The set output clock rates will not be altered; only the base rate will gradually be updated to match the new source using iCLOCK‘s SoftReLock functionality (see chapter iCLOCK TECHNOLOGY).

SYNCHRONIZATION This function allows for manual or automatic synchronization of the synthesizer to selected clock sources assigned to the REF1–3 slots.

SEQSYNC (setting)

SEQUENCE SYNCHRONIZATION This is the default setting when activating the REF1–3 menu page. It indicates the standard reference synchronization mode of iCLOCK.

REF 1, REF2, REF3 (setting)

If one of the REF1, REF2, or REF3 parameters is selected and confirmed by pressing the ENTER button, the synthesizer will immediately synchronize the clock source assigned to the corresponding REF slot. The output signals are set or adapted to the new source within the period specified by the LOCKTIME parameter (see GLOBAL 2/4 page).

CYCLESYNC (setting)

CYCLESYNC is not available when

the LONEREF function is set to HOLD

(see GLOBAL 2/4 menu page).

CYCLE SYNCHRONIZATION With this setting, the input circuit querys the three inputs for clock source reestablishment by cycling from REF1 to REF2 to REF3 and to the internal video reference generator automatically until a source is available. The system‘s priority is programmed to the first reference slot (REF1).

Refer to »Sequence Synchronization and Cycle Synchronization« section in the iCLOCK TECHNOLOGY chapter for details about SEQSYNC and CYCLESYNC.

If the optional second video generator is installed, it is necessary to split up the video output pairs between the two generators. Therefore, two jumpers have to be removed from their socktes on the mainboard, see the »Splitting-up the Video Ouputs for dual Video Generator Operation« section in the APPENDIX.

Locking the internal Video

Reference Generator – 1

If PAL or NTSC SD video is selected as external reference, the internal video reference generator will be automa-tically gen-locked by the reference source and switches to the same video format! This guaranties correct phase relationships between the video source and iCLOCK‘s generated sync signals. A video format conversion is only possible using the optional video generator P/NVSG-02 (Order no. 8010-010) additionally.

With synchronization to PAL or NTSC SD bilevel video it is not possible to change the clock reference (REF) of the internal video reference generator!

Configuring the internal Video Reference Generator

The settings of the internal video reference generator and the four video outputs available with iCLOCK standard version are configured on this page. Two output pairs comprising one top-row and one bottom-row BNC output each are available on the rear panel. These are numbered as PAL/ NTSC VIDEO OUT 1 and 2.

VIDEO page

VIDEO OUT 1 + 2 (page name)

VIDEO OUT 1 + 2 indicates that the internal video reference generator sends its signals to both PAL/NTSC VIDEO OUT 1 and 2. This means also that only one video reference generator is installed.

If the optional second generator is installed, another menu page will automatically be added for it. The page names will change accordingly:

VIDEO OUT 1 = internal video reference generator VIDEO OUT 2 = optional video generator

REF (function)

REFERENCE This function allows for setting the clock source of the respective video generator and can also enable video signal routing. The factory default is INTERN.

INTERN (setting)

INTERNAL links the video generator to the internal reference clock oscillator. An extraordinary feature of iCLOCK is that the synthesizer can be synchronized to an external clock source independently of the simultaneously enabled video generator. Therefore, only the audio-related clock signals might be subject to any present clock source deviation while the video signals are output with the accuracy of the internal clock: In a way, the video generator acts as »independent autonomous generator« within iCLOCK.

EXTERN (setting)

EXTERNAL This setting synchronizes the video reference generator to the currently selected external clock source. Any signal or phase relations between the input clock signals and the selected video format will be recognized automatically and be routed internally in compliance with AES11 and EBU R83.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

ANHANG

\\\\\\\\\\\\\\\\\\

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

This function also ensures a redundant (failsafe) availability of the video output signals. If the external source fails temporarily or permanently, the video generator will continue generating its output signals based on the last recognized clock rate. If the external source returns to operation, any differences to the previous rate will gradually be corrected to maintain flawless on-air operation in e.g. broadcasting environments.

DIST (setting)

DISTRIBUTION This setting allows for forwarding the input video signal to the video outputs using a hardware bypass. The signal is refreshed by the video generator output amplifier to ensure a suitable output level; no other modifications are made to the signal. If the DIST setting has been selected for REF, the FORMAT and VIDEO TYPE functions cannot be selected anymore. This is because the video output format is determined by the input video reference signal.

In this mode, the synthesizer synchronizes to the input video signal to provide the output of phase locked audio clock signals.

FORMAT (function)

FORMAT This function allows for selecting the video format generated and output by the video generator. The factory default is PAL.

PAL (setting)

PAL With this setting, the video generator produces a PAL-B/G standard definition (SD) video signal compliant with the PAL/CCIR video standard (25 fps, 625 lines, 15,625.0 Hz line frequency). Depending on the REF and VIDEO TYPE settings, this signal can be output as Black + Burst or composite video sync. Even when a HD tri-level source is choosed as reference (HD-P-1 / 2), the PAL setting is possible. Thus the internal video reference generator directly converts incoming HD references with frame rates of 24Hz, 25Hz, 30Hz, 50Hz or 60Hz into PAL SD video using its unique cross-locking functionality.

NTSC (setting)

NTSC With this setting, the video generator produces an NTSC standard definition (SD) video signal (29.97 fps, 525 lines, 15,734.25 Hz line frequency). Depending on the REF and VIDEO TYPE setting, this signal can be output as Black + Burst or composite video sync. Even when a HD tri-level source is choosed as reference (HD-N-1 / 2), the NTSC setting is possible. Thus the internal video reference generator directly converts incoming HD references with frame rates of 23.98Hz, 29.97Hz or

59.94Hz into NTSC SD video using its unique cross-locking functionality.

Refer to the »Synchronizable HD tri-level Standards and Frame Rates« section in the APPENDIX for a list of all convertable HD standards and frame rates.

VIDEO TYPE (function)

VIDEO TYPE This function allows for outputting the previously selected video format as Black + Burst or composite video sync signal. In addition, when selecting composite video sync, one of two different output levels can be set (see below). The factory default is BLACK + BURST.

BLACK + BURST (setting)

BLACK + BURST With this setting, the signal of the previously selected format will be output as Black + Burst signal. Refer to the »Technical Data« section in the APPENDIX.

COMPOSITE SYNC 0.3V (setting)

COMPOSITE 0.3V With this setting, the previously selected video format is output as composite video sync signal with a negative sync signal level of 300 mV (0.3 V).

COMPOSITE SYNC 2.0V (setting)

COMPOSITE 2.0V With this setting, the previously selected video format is output as composite video sync signal with a negative sync signal level of 2.0 V.

Locking the internal Video Reference Generator – 2

When running the internal video reference generator in EXTERNAL mode, the external reference signal may not deviate more than ±30 ppm from its nominal clock frequency! Do not try to lock the video generator to pull up/down clock rates - its video signal would be destroyed!

DIST does not provide redundancy for the video outputs. If the external video reference source fails, the video outputs will fail, too!

Locking the internal Video

Reference Generator – 3

When externally synchronizing the video reference generator, the lock and varispeed ranges of the synthesizer will be reduced to ± 30 ppm! Thus, enabling the pull-up/down and varispeed factors is not provided in this mode. If, however, these settings are made, the video generator will automatically enable internal synchronization.

When locking the synthesizer to the internal video reference generator or when locking the video reference generator to an external applied reference source, a synchronization time of approx. 30 seconds for attuning all components of the video output signal is required.

Configuring the Word Clock Outputs

Due to the internal signal phase corrections the synthesizer can re-lock temporarily when switching Word Clock clock frequencies. This does not affect the output signals or functionality of iCLOCK.

The WCLK OUT 1–4 display pages allow for configuring the eight wordclock outputs provided by the iCLOCK standard version . Four output pairs comprising one top-row and one bottom-row output each are available on the rear panel. These are numbered as WORD CLOCK OUT 1–4. The BNC terminals making up a pair are marked as »A« and »B«, thus allowing for a simple documentation of the connected devices.

GPS / Atomic Clock + Audio Player References

As so-called GPS or atomic clock references, the iCLOCK and iCLOCKdp are able to lock and generate the following frequencies:

1.0Mhz, 2.5MHz, 5.0MHz, 10.0MHz

Furthermore, the iCLOCK and iCLOCKdp are able to generate the following basic clock rate used in e.g. CD players:

16.9344MHz

This clock signal can be used to replace a CD player‘s internal system clock with the

16.9344MHz clock signal generated by the iCLOCK or iCLOCKdp. Thus, a CD player can benefit from the iCLOCK‘s lowest-jitter clock generation which leads to an audible sound improvement of the CD player‘s DA converters!

Before replacing your CD player‘s internal basic clock, check carefully if the frequency of 16.9344MHz is the right one for your CD player!

24.576 MHz can be selected individually for each Word Clock output pair. Also 8 pilot tone clock rates from 24 Hz to 60 Hz are available for synchronizing pilot tone resolvers, timecode generators or film projectors and 5 different high-accurate clock references known from GPS receivers or atomic clock generators. The individual rates are shortly described under <

FORMAT>. Refer to the »Synchronizable and Generatable Clock Rates«

section in the appendix for a full list of all clock rates.

‹FORMAT› (message)

LEVEL / TERM (function)

LEVEL / TERMINATION This function allows for adjusting the Word Clock signal level of the selected output pair and for entirely disabling the output. The page always displays the output level and the corresponding internal termination of the output pair. The factory default is 2.6 V/75 R.

2.5 V / 75 R (setting)

With this setting, the Word Clock signal is output with a level of 2.6 V and an internal termination of 75 Ω .

3.5 V / 22 R (setting)

With this setting, the Word Clock signal is output with a level of 3.5 V and an internal termination of 22 Ω. This setting is recommended for Word Clock signals to be transmitted over great distances.

SC adapted (setting)

SUPER CLOCK adapted This is no adjustable setting but a status message used only for clock rates set to Super Clock. Here, the level cannot be modified but only be disabled if required (OFF).

OFF (setting)

OFF disables the selected Word Clock out pair.

More Clock Frequencies

For special-purpose applications, the range or number of the output clock frequencies can be extended by means of a software update. Practically any frequency or frequency range between 1.0 Hz and 25.0 MHz can be defined and can then be selected for all Word Clock outputs, providing the same functionality as the standard frequencies.

AES – SINGLE, – LINKED The »S« and »L« letters shown on each of the two AES/EBU menu pages indicate the Single and Linked modes. Refer to the ADJ-AES/EBU parameter on the GLOBAL 3/4 page explained in the SETTING SYSTEM FUNCTIONS chapter for more information. The factory default is Single mode (– S).

OUT 1/1, -1/2, -2/1, -2/2 (page name)

The page name contains the selected AES/EBU-output pair (1 or 2) and the number of the currently displayed menu page. The pages AES OUT 1/1 and AES OUT 1/2 allow for configuring the first output pair while the pages AES OUT 2/1 and AES OUT 2/2 are used for the second output pair.

When a certain Word Clock out pair is not required, disabling it can be reasonable, for example, to reduce extra device radiation, thus improving the EMC conditions in the studio.

(EMC = electromagnetic compatibility)

Due to the internal signal phase corrections the synthesizer can re-lock temporarily when switching AES/EBU clock frequencies. This does not affect the output signals or functionality of iCLOCK.

Functions and settings on the first page of each AES/EBU output pair:

FREQ (function)

FREQUENCY Sets the clock rate of the selected AES/EBU output pair. A socalled AES11 clear-frame signal (compliant to AES 11-1997/2003) is generated. The factory default is 44.1kHz.

16.0...192.0kHz (setting)

Altogether twelve different clock rates between 16.0...192.0 kHz can be individually selected for each AES/EBU-out pair. Refer to the »Synchronizable and Generatable Clock Rates« section in the appendix for a full list of all clock rates.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

AES3/-11 clock rates are set independently of externally applied clocks. Thus, iCLOCK provides AES3/-11 clock conversion from all supported input rates to all generatable output rates!

ANHANG

\\\\\\\\\\\\\\\\\\

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

DIST (setting)

DIST does not provide redundancy for the AES/EBU outputs. If the external AES/EBU or S/P-DIF clock source fails, the associated AES/EBU-output pair will fail, too!

DISTRIBUTION This setting allows for forwarding an input AES3 or S/P-DIF signal to the selected AES/EBU output pair using a hardware bypass. As no adjustments can be made in this mode, the other functions and parameters will be hidden, and the second menu page of the AES/EBU pair will not be accessible; the parameters and functions can only be accessed after the internal AES11 generator has been enabled by selecting a different clock rate.

In this mode, the synthesizer synchronizes to the input AES3 or S/P-DIF signal; thus, the video and audio clock signals provided at the other outputs are linked with phase lock to the input signal.

WORDL (function)

If the consumer format is selected, the physical parameters of the output terminals (balanced operation, level, and impedance) will remain unchanged!

The functions and settings displayed on the AES menu pages are automatically adapted with regard to the channel-status bits of the consumer format.

WORD LENGTH This function allows for changing the word length stored in the channel status bits (byte 2, bits 3, 4 and 5) of the clear-frame signal of the selected AES/EBU output pair. The factory default is 24BITs.

16BITs, 18BITs, 20BITs, 24BITs (setting)

One of four word lengths between 16 and 24Bits are available for selection.

FORMAT (function)

FORMAT This function allows for altering the AES format stored in the channel status bits (byte 0, bit 0) of the blank frame signal of the selected AES/EBU output pair. The factory default is PROF.

PROF, CONS (setting)

PROF, CONS This setting allows for toggling the AES11 blank frame signal between consumer (CONS) and professional (PROF) formats.

Example

There are AES3/-11 receiver circuits causing problems when synchronizing to AES11 blank frame signals. This usually results in increased jitter and signal instabilities. Enabling a DC-offset level in the AES11 blank frame signal will allow for synchronizing any AES3/-11 input stage. This level can normally be processed without problems by the concerning AES3/-11 input stages, thus ensuring reliable synchronization.

DCSET (function)

DC OFFSET This function allows for applying a DC-offset signal level of approx. 200 mV to the output AES11 blank frame signal.

ON, OFF (setting)

This will enable (ON) or disable (OFF) the DC-offset signal level in the AES/EBU blank frame signal.

Functions and settings on the second page of each AES/EBU output pair:

AUDIOSTAT (function)

AUDIOSTATUS This function allows for setting the audio status stored in the channel status bits (byte 0, bit 1) of the blank frame signal of the selected AES/EBU output pair. The factory default is NONAUDIO.

NORMAUDIO, NONAUDIO (setting)

These settings allows for selecting the norm-audio or non-audio statuses.

REFSTAT (function)

REFERENCE STATUS, This function allows for changing the reference status stored in the channel status bits (byte 4, bits 0, 1) of the blank frame signal of the selected AES/EBU output pair. The factory default is G1-REF.

G1-REF (setting)

GRADE 1 REFERENCE With this setting (grade 1 reference), the AES11 blank frame signal is output in compliance with AES11, Grade 1.

G2-REF (setting)

GRADE 2 REFERENCE With this setting (grade 2 reference), the AES11 blank frame signal is output in compliance with AES11, Grade 2.

NO REF (setting)

NO REFERENCE This setting indicates that the AES11 blank frame signal is not a reference signal compliant to AES11.

LOCKSTAT (function)

LOCK STATUS This function allows for changing the synchronization status stored in the channel status bits (byte 0, bit 5) of the clear-frame signal of the selected AES/EBU output pair. The factory default is LOCKED.

If the selected AES/EBU output pair is operated in consumer mode, this parameter is not available due to the modified structure of the channelstatus bits!

LOCKED, UNLOCKED (Parameter)

LOCKED, UNLOCKED These settings allow for toggling between the locked and unlocked statuses.

Configuring the S/P-DIF Outputs

A clock rate can be set for both S/P-DIF outputs similarly. The channel-status bits can be modified, too.

The preset management enables to store eight different set-ups of all function settings which have been set within the whole iCLOCK system menu, as so-called ‚Presets‘. When switching over the presets, all individual function settings will be switched at one time. Additionally, the preset management stores intermediately the whole current system status permanently in a socalled ‚System-Preset‘. This system-preset works fail-safe, which provides an automatic function-setting-recovery after, e.g., a mains failure!

When switching on your iCLOCK or iCOCKdp for the first time, all presets contain of the same factory default settings as described in the previous chapters of this manual. This system condition is equal to this one after a software-reset.

After normal switching on the unit, the last system status stored in the system-preset will be loaded. If this is different compared to the settings of the last active preset, the selected setting under the function OPERATION will be marked with a (*). If you want to work with the current system status, you have to store it in one of the eight available presets. If you prefer to work with that preset, which was active before last switching off / on the unit, you have to load this preset separately.

But if the GPIO preset control is active, your iCLOCK or iCLOCKdp starts using the preset which was previously active, no matter if the system-preset consists of different settings, which are due to changes before switching of the unit.

BEDIENELEMENTE

Example

iCLOCK is synchronized by an external Word Clock reference with 44.1kHz. The outputs are adjusted to different clock rates (see adjacent diagramm). If the external reference changes to 48.0kHz, the predefined outgoing clock rates will remain unchanged!

The reason is that iCLOCK‘s intelligent synthesis process synchronizes every reference signal phase-locked and converts it simultaneously into the adjusted output clock rates. Thus the typical signal distribution effect, »a change of input clock rate changes all output clock rates«, is prevented in general. The adjusted output clock rates are permanently available, not depending on the frequency or format of the incoming reference!

iCLOCK TECHNOLOGY

Functional Principle

iCLOCK‘s principle operation is completely different to conventional products. The customer, as a matter of priority, defines the clock rates and formates which are constantly available at the outputs – not depending on the incoming reference signals! Limitations regarding defined combinations of input and output clock signals do not exist for iCLOCK. All inputs and outputs can be routed and combined freely.

Input Reference Change

44.1kHz to 48.0kHz

Output WCLK

Output WCLK

Functional principle during input reference change

Furthermore, unlike standard clock generators, iCLOCK‘s unique concept enables to set all system functions during any operation mode. This is regardless of whether the synthesizer is synchronized internally or by an external source. Doing this, the powerful synthesis process enables additionally, as an outstanding feature, the use of the pull up/down and varispeed functions simultaneously! Thus any conceivable adaption of the outgoing basic clock rates is possible with iCLOCK.

During this process the system detects automatically useful phase relationships between the reference input and generated output signals. Adjustments aligned to AES11-1997/2003 and EBU R83-1996 will be executed in realtime independently.

Output WCLK

176.4kHz

Output WCLK

SoftReLock

SoftReLock is a special system routine executed by the synthesizer in every operation mode of reference change or reference resynchronization. Especially in cases of the later described SEQSYNC or CYCLESYNC functions, SoftReLock guarantees a gradual and seamless synchronization update of the internal signal generators, or all iCLOCK output signals respectively, to the basic clock rate of a new or reestablished reference source. Also if complete different reference types of unequal sources are synchronized in succession, e.g. NTSC video after pulled down 48.0kHz AES11, the SoftReLock routine ensures interruption-free and gently adjustment of iCLOCK‘s output signals to the new reference.

SoftReLock represents one of the most important functions to support the system‘s ability providing continous clock supply under all imaginable operation modes.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

CLOCK TECHNOLOGY

As the clock source selected as REF1 has always the highest priority for synthesizer synchronization, the CYCLESYNC function will always try to synchronize to REF1 first, then to REF2, to REF3 and finally to the internal video reference generator.

Example

If the first source (REF1) has failed, the synthesizer tries to synchronize the next source (REF2) after passing the LONEREF timing interval (A). When a second source is available and synchronized finally (after passing the LOCKTIME timing interval, B), 10 seconds later the system starts querying REF1 for source reestablishment again. If the system finds a utilizable source signal within the defined LONEREF period, it will resynchronize to the REF1 signal.

When no reference is available at REF2 the system waits until the timing interval of the LONEREF function (A) has elapsed and starts to check REF3 for a clock source. If REF3 is set to »NO REF« the system skips this reference slot and synchronizes the internal video reference generator under consideration of the LOCKTIME timing interval (B).

Note! Reference slots marked with »NO REF« will be not recognized by CYCLESYNC.

Example

If the first source (REF1) has failed, the synthesizer tries automatically to synchronize the next source (REF2). When no reference is available the system waits until the timing interval of the LONEREF function (A) has elapsed to synchronize the next reference. Is a clock source present, the synthesizer starts to synchronize this under consideration of the LOCKTIME timing interval (B). If this reference also fails the system checks for the third source (REF3) in same procedure.

Note! If a reference slot is set to »NO REF« the system skips this slot and synchronizes the next activated slot or the internal video reference generator.

The system will be locked as long as a clock source is available at the respective reference slot. But after synchronizing the next further reference it will not try to resynchronize the previous one if this has returned. If no utilizable signal is present on the three slots, the synthesizer will synchronize the internal video reference generator as the final clock source. After this a returned external source will be not synchronized any more.

iCLOCK EXTENSIONS

iC-ALARM up to operating system V2.10

The optional iC-ALARM interface (ordering no. 8005-065) is only suitable for iCLOCK software versions up to V2.10. From V2.11 you must (!) use the iC-ALARM/GPI interface, see below.

The iC-ALARM interface enables to trans-fer signals depending on three different critical operating conditions. Each of the potential-free alarm outputs is directly coupled to a floating change-over relay and is designed as an individual pin of the 15pins high-density D-Sub connector. Thus all three alarm signals can be transfered simultaneously. The relays change their states instantly when the following operating conditions are present:

ALARM OUT 1: Loss of clock reference at the currently active input ALARM OUT 2: Loss of Main1 or Main2 (or circuit), only iCLOCK dp ALARM OUT 3: Loss of the internal reference oscillator

Every of the above mentioned operating conditions activate also the red front panel LED »ALARM set«.

The relays are normalled when the described operating conditions work faultlessly. If a disturbance occurs, the according relay faills instantly. The output contacts supply a max. switching power of 30 W with 30 V / 1A DC / AC peak. The type of the used relays is called TQ2-5V from NAIS / Matsushita (http://www.nais-e.com/relay/index.html).

iC-ALARM/GPI from operating system V2.11 or higher

The optional iC-ALARM/GPI interface (ordering no. 8005-066) is only suitable for iCLOCK software version V2.11 or higher.

The iC-ALARM/GPI interface offers same basis functionality like the previously described iC-ALARM. New to the iC-ALARM/GPI interface is its GPIO function (see page 31).

General Function Description

The iC-ALARM/GPI interface enables to transfer signals depending on three different critical operating conditions. Each of the potential-free alarm outputs can be individually set as closing or opening contact by using different jumper settings on the interface‘s PCB. Furthermore, every output is directly coupled to a floating change-over relay and is designed as an individual pin of the 15pins high-density D-Sub connector. Thus, all three alarm signals can be transfered simultaneously. The relays change their states instantly when the following operating conditions are present:

ALARM OUT 1: Loss of clock reference at the currently active input ALARM OUT 2: Loss of Main1 or Main2 (or circuit), only iCLOCKdp ALARM OUT 3: Loss of the internal reference oscillator

Every of the above mentioned operating conditions activate also the red front panel LED »ALARM set«.

Furthermore, when running system V2.11 or higher in your iCLOCK or iCLOCKdp, you can take advantage of the interface‘s new GPIO functionality. This enables to switch over the 8 user presets from remote work spaces or central control rooms.
