HD-TD-3GMX-2 / HD-TD-3GDX-2 and SDI-TD-3GMX-5 / SDI-TD-3GDX-5 Rev. F

1 The multiplexer / de-multiplexer pair at a glance

The SDI-TD-3GMX-5 is a Flashlink time-division multiplexer (TDM) that either allows any
pair of supported HD-SDI or SD-SDI inputs or a single HD-SDI or SD-SDI input, plus up to
4 SD-SDI inputs to be transported over a single 3GHD-SDI link.

The SDI-TD-3GDX-5 is a Flashlink time division de-multiplexer that either recovers the 2
HD-SDI/SD-SDI streams or the single HD-SDI/SD-SDI stream plus 4xSD-SDI streams from
the 3GHD transport signal. The selection is automatic, based on what is detected in the
stream.

The HD-TD-3GMX-2 is a Flashlink time-division multiplexer (TDM) that allows any pair of
supported HD-SDI or SD-SDI inputs to be transported over a single 3GHD-SDI link.

The HD-TD-3GDX-2 is a Flashlink time division de-multiplexer that recovers the 2 HD­SDI/SD-SDI streams from the 3GHD transport signal.

Other key features of the multiplexer / de-multiplexer pair include:

 Supports all the most common video standards including SDTI.
 Accepts any combination of synchronous or asynchronous HD-SDI 1485 Mbps or

SD-SDI 270 Mbps input formats, as long as the video standard is supported. Correct
video formats will be recovered at the de-multiplexer end.

 Separate stream clock reference data for each channel is transferred for remote

clock regeneration. Correct clocks will be recovered at the de-multiplexer end.

 Automatic input format detection for each channel.
 All streams embedded in the 3GHD transport signal are completely independent. No

cross-contamination of the other stream when one input is lost.

 Low latency.
 Can be combined with SDI-TD-MUX-4 and SDI-TD-DMUX-4 modules to transport

up to 8 SD-SDI channels over one 3GHD link.

 High performance optics for short and long haul applications available, including

CWDM and DWDM.

 Optical and electrical 3GHD TDM outputs are available simultaneously from the

multiplexer cards, if purchased with an optional laser.

 Change-over functionality between de-multiplexer electrical and optical inputs.
 The transport signal is compliant with the SMPTE-425M Layer B standard and will

always be marked as 1080/30P. Standard 3GHD infrastructure can be used to
transport the multiplexed signal.

 Multicon interface allows remote control, status monitoring, error reporting and

SNMP support.

 The HD-TD-3GMX-2 and HD-TD-3GDX-2 can be field upgraded to the SDI-TD-

3GMX-5 and SDI-TD-3GDX-5 respectively if the need arises.

4.1 The HD-TD-3GMX-2 and HD-TD-3GDX-2

Figure 1: Logical building blocks for the HD-TD-3GMX-2(-T)

Figure 2: Logical building blocks for the HD-TD-3GDX-2(-R)

The HD-TD-3GMX-2 board embeds up to two independent HD or SD video streams in one
output 3G stream. After the two HD or SD streams have been remapped, to avoid synch­word conflicts with the transport stream frame, they are embedded in a 2.97 Gbps (3GHD)
stream in a proprietary protocol which is still compliant to the SMPTE 424-2006 and
SMPTE 425-2006 Level B standards. In order to reduce latency, the streams are
embedded asynchronously to each other and to the transport stream. The combined
latency of the HD-TD-3GMX-2 and HD-TD-3GDX-2 boards is always well below 100µs.

If the two HD streams were fully synchronous when entering the HD-TD-3GMX board, they
can have individual phase shifts of several samples after being demultiplexed at the HD­TD-3GDX-2 end, but the clock frequencies will be the same as soon as the system has
stabilized (after a few seconds).

After demultiplexing in the HD-TD-3GDX-2 board, the data structure that was remapped on
the sender side will be restored and the data rate (pixel clock) will also be restored to
exactly the same rate as it was received on the HD-TD-3GMX-2 board.

The 3G signal is seen and transported as a standard 3G-SDI Level B (1080/30p) video by
external equipment. No other format can be set at the sender side of the link and no other
format will be accepted at the receiver side of the link. An HD-TD-3GDX-2(-R) or an SDI­HD-3GDX(-R) board is required to reconstruct the two HD signals from the 3GHD at the
receiving end.

Note that frame synchronization or switching of the 3G transport signal should
be avoided, as switching or repeated/deleted frames will cause severe signal
failures in the recovered streams at the receiving end of the link.

HD-TD-3GMX-2 / HD-TD-3GDX-2 and SDI-TD-3GMX-5 / SDI-TD-3GDX-5 Rev. F

The HD-TD-3GMX-2 can receive any combination of two HD or SD video standards,
synchronous or asynchronous. The HD-TD-3GMX-2 embeds timing information that the
HD-TD-3DX-2 uses to regenerate the HD or SD signals with the same clock frequency as
the original inputs. The two signals are treated as two completely independent streams,
which means that there will be no cross-contamination of the other stream when one input
goes missing or has inherent errors.

The output from the HD-TD-3GMX-2 module is either electrical 3G-SDI according to the
SMPTE 425M standard, or if an optional laser module is added, simultaneous electrical and
optical 3GHD-SDI according to SMPTE 297-2006

If the customer has purchased an optional long haul or short haul receiver module for the
DMUX side (in which case the DMUX module will have an “R-L” or “-R” appended to its
name), there will be an option available to select either input manually, or to select between
them automatically.

4.2 The SDI-TD-3GMX-5 and SDI-TD-3GDX-5

The SDI-TD-3GMX-5 has two distinct modes of operation, set by the user: Either the same
two-input mode described above for the HD-TD-3GMX-2 / HD-TD-3GDX-2, or a mode with
up to five inputs, where only the first one can be HD-SDI. The latter mode is really the same
as the first, but with the addition of a 4xSD-to-1xHD software module from the SDI-TD­MUX-4. This means that the HD stream normally coming straight from input 2, will now be
replaced with a multiplex of four SD-SDI inputs. This in turn means that input 2 can only
handle SD-SDI input signals in this mode, not HD-SDI. The user selection of the two modes
will prevent the possibility of overflowing the 3GHD-SDI carrier stream.

On the de-multiplexer side of the 3G transport link, the card will be able to read control
words embedded in the transport signal to determine which mode it should operate in. No
user control is necessary on the de-multiplexer side. The SDI-TD-3GDX-5 fully supports
input from both the SDI-TD-3GMX-5 and the HD-TD-3GMX-2, whereas the HD-TD-3GDX-2
will only be able to recover the signals for outputs 1 and 2 if fed a signal from an SDI-HD­3GMX-5.

4.3 HD ancillary data limitations

Because the total usable transport bandwidth in the 3G output of the multiplexer is slightly
less than that of two full HD streams, a small number of samples must be dropped from the
incoming horizontal blanking intervals. The active picture will never be affected.

The number of samples dropped varies depending on the HD format as shown in Table 1.
Samples will be removed from the tail end of the HANC, following a left-alignment of all

valid packets. Given typical HANC payload size, such as required to carry AES audio, the
sample deletion will have no impact as it will occur entirely in unused samples.

In the case of an unusually full HANC, such that sample deletion would result in a
fragmented HANC packet, the remaining fragment will be deleted to maintain SMPTE
compliance.

HANC data that are not contained within a valid SMPTE 291M packet are not guaranteed to
be transported, and may appear as null or ’black’ values when de-multiplexed.

There are no limitations to the active video area portion of the HD signal to be
transferred – this will always be restored to its original content at the receiving
end of the link, as long as it is a valid video signal according to applicable
SMPTE standards.

5 Configuration and monitoring

Both multiplexer and de-multiplexer cards are self-configuring in the sense that they will
start working according to default factory settings once power and input signals are applied.
HD-SDI or SD-SDI video standards will be detected and handled automatically.

5.1 Configuration

Configuration parameters can be changed in two ways: via changes to the DIP switches or
via the system controller Multicon GYDA. The lower DIP switch of the module is labeled
OVR. If this DIP is set to the ON position, the module will not accept commands from the
Multicon system controller, but will instead be controlled entirely by the position of the rest
of the DIP switches. Multicon GYDA will however be able to monitor the module and
retrieve the current configuration (this will be stored to enable hot-swap functionality with
another module under Multicon control). Conversely, if the OVR switch it is set to the OFF
position, the other DIPs are disregarded altogether and the module is under full Multicon
GYDA control. As delivered from the factory, all DIPs should be in the Off position. The
module will then be under Multicon GYDA control.

5.1.1 Configuring the multiplexers from Multicon GYDA

The HD-TD-3GMX-2 product contains a subset of the features found in the SDI-TD-3GMX-

5. The description below contains blocks that will only be found on the full featured product,
the SDI-TD-3GMX-5. The picture of the HD-TD-3GMX-2 configuration page is provided for
reference, see Figure 4.

Starting from the top of the page on the SDI-TD-3GMX, the following things can be
set/adjusted:

Card label: This field enables the user to set a name for each module (Actually, it’s the slot
in the frame, as the label will persist even if the card/backplane combination is replaced by
a completely different module). The name will show up above the card type on the info
page and on the configuration page, and it will also be shown as a mouse-over text when
the mouse cursor is held over the card’s icon in the pictured rack.

Locate card: Flashes the 4 LEDs on the front of the module at about 0.5 Hz for the number
of seconds the user specifies. This is intended to help find a card quickly in a large setup.

Firmware upgrade: The firmware for the onboard microcontroller and the FPGA can both
be upgraded, if needed. This red line only shows up if the Multicon GYDA system controller
has found a folder containing Flashlink firmware files. Contact Nevion Support if you need
an updated firmware.

Mode of operation: (Stored setting) The multiplexer can work in two distinct ways. It can
simply pack two HDs into one 3G stream, or it can pack 4 SDs into one HD before packing
the resulting HD with another HD from input 1. In the first case, the 2 HDs can each be
replaced with a single SD, but still only transport 2 channels over the 3G transport stream.
This will be handled automatically. In the second case, the HD on input 1 can be replaced
with an SD signal. This will also be handled automatically. The other 4 inputs will only
accept SD, and any HD signal on these inputs will simply be ignored.

The reason for splitting the operation into two modes can be seen when considering what
would happen when the card was fed 2 HDs and 3 SDs simultaneously. It would obviously
not be possible to transport all these signals over one 3G stream, so something has to be
given priority over the other inputs. The key is really whether input 2 is HD or SD, so if this
toggled between HD and SD, it would not only mean that one channel was unstable, it
would also affect whether inputs 3-5 would be transported or not. Hence the user is made
to make the choice. A corner case is when the mode is set to be HD/SD+4xSD and inputs
3-5 have no signal at all. In that case it is possible to transport an HD from input 2 (and it

nevion.com | 13

HD-TD-3GMX-2 / HD-TD-3GDX-2 and SDI-TD-3GMX-5 / SDI-TD-3GDX-5 Rev. F

will be!), but it is a fragile state, as it will immediately be replaced with one or more SDs as
soon they’re detected on inputs 3-5.

Input integrity 1…5: (Stored setting) The user can select which errors should be counted
and which can be ignored. The CCS and YCS count settings work as a pair, meaning that
both will either be counted or both will be ignored. If the user makes a change to one of
these bits, the module assumes that the new setting should be applied to both bits. The
web page will always be updated to show the actual setting. The CCRC and YCRC error
bits also work as a pair.

The available error bits are as follows:

EAV – End of active video error
SAV – Start of active video error
LNUM – Line numbering error (HD only)
YCRC – Luma CRC error (HD only)
CCRC – Chroma CRC error (HD only)
YCS – Luma checksum error
CCS – Chroma checksum error
LOCK – Lock error
AP-CRC – Active picture CRC error (SD only)
FF-CRC – Full frame CRC error (SD only)
VS – Video standard error

Inputs 3-5, which are SD only, will not have LNUM, YCRC or CCRC errors available, since
these only have meaning for HD.

Laser: (Stored setting) The only setting available for the laser is power On or Off. All other
settings should already be done at the factory.

The laser module is optional. Boards with factory mounted laser will have “-T” appended to
the module’s name, and only they will display the laser block in the graphical user interface.

5.1.2 Configuring the de-multiplexers from Multicon GYDA

Figure 5: The SDI-TD-3GDX-5 configuration page in Multicon GYDA.

Starting from the top of the page, the following things can be set/adjusted:

Card label: See multiplexer description.
Locate card: See multiplexer description.
Firmware upgrade: See multiplexer description.
Input select: (Stored setting, only available when an optional optical input is installed). This

control is only available for boards with the optional optical input. Here the user can select
to force the input to be taken from either the electrical or the optical input, or allow the card
to automatically select between them.

In manual mode there is no fallback to the other input available at all. In auto mode, there’s

always a fallback to the other input available, the user only has to select which input is
considered the main input. The other is considered the backup.

The input selector is always latching. This means that if the input selector has (for some
reason) switched away from main to the backup, the selector will continue to stay in this
position until either the user selects to push the latch reset button, or the backup disappears
(at which point the logic will start to look for a valid input on either of the two inputs, but
starting with the main input).

Through the “hold time” and the “latch time” the user can select how long the module will
cling on to a lost signal and hope that it will reappear, and how long a signal must be
present before it is considered valid and stable, respectively.

Integrity of 3G TDM input: (Stored setting) Sets the maximum error rate or the maximum
number of errors that can be present before Multicon GYDA sets off an alarm. Also sets
which types of errors should be counted and which should be ignored. See input integrity in
the multiplexer section for a description of the error bits.

A factory reset is a 3 step process:
* Set Factory reset DIP to the ‘On’ position and boot the card (The Control

mode must also be set to Manual mode).
* Remove power and set the reset switch back to normal position (Off)
* Power up the card as normal.

HD-TD-3GMX-2 / HD-TD-3GDX-2 and SDI-TD-3GMX-5 / SDI-TD-3GDX-5 Rev. F

The operation of the card will immediately reflect the freshly loaded default settings.
However, the card must be kept powered for at least 10 seconds to ensure that these
settings are stored locally to be retrieved again at the next start-up. The card’s operational
environment must also be kept static during those 10 seconds (i.e. no change in incoming
video standards, no commands issued). Failing to meet these requirements could result in
an incomplete reset and require the user to restart the factory reset sequence.

5.2 Monitoring

5.2.1 The information page for the multiplexer cards

The information page shows a dynamic block diagram of the board and some additional
information in text form. The block diagram updates with the board status, showing missing
signals (by red crosses over the appropriate signal lines).

The text table on the information page gives additional information not easily conveyed in a
graphical manner.

From the text table, we can read the following: Both cable equalizers are enabled
(“Normal”), as opposed to “Bypassed”. None of the two reclockers has been able to lock to
a legal input. That the reclockers are unlocked can also be seem from the two red crosses
over the signal lines to the right of the reclocker boxes. When the reclockers are locked, the
bit rate will be indicated.

The error counter has found no errors for input 1 or 2 (at least not errors of the types that
are set be counted). We can also tell that the voltages are reasonably close to their nominal
values.

If this were a board with the laser option, the table would display an additional line like this:

Here we can see that the laser is powered and what kind of laser it is (wavelength, power
and type).

5.2.2 The information page for the de-multiplexer cards

From the text table, we can read the following: The electrical input has been manually
selected. This (and the name of the module) also indicates that this board has the optional
optical input installed. No carrier is detected on the optical input.

The error counter has found no errors for the HD input (at least not errors of the types that
should be counted). We can also see that the voltages are reasonably close to their
nominal values (It is quite normal for the 5V supply to be 0.1V – 0.2V under its nominal
value).

6 Using the cards with the SDI-TD-MUX-4 and SDI-TD­DMUX-4

The SDI-TD-MUX-4 can be used to multiplex 4 SD-SDI signals into a single HD-SDI. This
HD-SDI signal can in turn be used as input to the HD-TD-3GMX-2 or the SDI-TD-3GMX-5.
This means that is possible to embed up to eight SD-SDI signals on one 3G transport signal
with the use of either two SDI-TD-MUX4 + one HD-TD-3GMX-2 or one SDI-TD-MUX-4 +
one SDI-TD-3GMX-5. In addition, one SDI-TD-MUX4 + one HD-TD-3GMX-2 can effectively
be used together as one SDI-TD-3GMX-5, but at a slight penalty in the power consumption
and by using two rack slots instead of one.

The de-multiplexer side should normally be a mirror of the multiplexer setup. Although the
SDI-TD-DMUX-4 (and indeed the SDI-TD-MUX-4) has built-in matrices for routing
(‘shuffling’) the four SD-SDIs, it’s not possible to do any routing on the HD-SDI level.

7 Connections

7.1 Power connections

Power is applied to the board via the backplane board, which in turn is plugged into the
power distribution bus in the Flashlink rack.

The HD-TD-3GMX-2 and SDI-TD-3GMX-5 boards both consume 5.0 W of power from the
+5 V supply and 1.5 W of power from the +15 V supply.

The HD-TD-3GDX-2 and SDI-TD-3GDX-5 boards both consume 3.7 W of power from the
+5 V supply and 1.7 W of power from the +15 V supply.

For all boards, this means that some power supplies will limit the number of
cards per frame to less than 10 (a fully populated frame). Check the power
ratings of the supply you plan to use!

7.2 Backplane

All cards mentioned in this manual use the same backplane. The direction of each BNC
port will depend on whether it is used with a multiplexer or a de-multiplexer board.

Table below shows the signal directions for the SDI-TD-3GMX-5 board, with the directions
for the SDI-TD-3GDX-5 in parentheses.

The GPI I/Os consists of alarm signals for driving external alarm devices and one input to
disable the laser output for the SDI-TD-3GMX-5/HD-TD-3GMX-2. See chapter 7.2.1.

7.3 The main board

There are also a number of connectors on the board itself. None of these are intended for
the end-user.

nevion.com | 27

HD-TD-3GMX-2 / HD-TD-3GDX-2 and SDI-TD-3GMX-5 / SDI-TD-3GDX-5 Rev. F

The rear end of the boards (with the connector that mates to the backplane) is towards the
right side of the board. The boards must be mounted in a Flashlink FR-2RU-10-2 frame with
dedicated backplanes. Avoid inserting the HD-TD-3GMX-2 or the HD-TD-3GDX-2 board
into a non-compatible backplane, as this may cause electrical and/or mechanical damage
to the main boards and/or the backplane.

Exceptions for the LEDS:
The locate command will make all four LEDs blink orange and off

synchronously. The operation of the card will not be affected.
If only the Card status LED blinks between orange and off, this means that the

mounted DWDM module is either too hot or too cold to output the correct
wavelength, and that the output has temporarily been shut off. If this occurs
other than for a short moment immediately after start-up, the thermoelectric
element on the DWDM module is most likely broken.

Firmware upgrades will activate running lights on the LEDs after the firmware
download has finished. Do not remove power to the card when running lights
are active, the card is unpacking and installing the new firmware. The modules
will automatically reboot after a successful upgrade.

Video monitors (MUX)

The vmon blocks 0-1 consist of an
error counter for each HD input. Each
error counter can be reset with its
reset command. Which errors are to
be counted is set for each error
counter with its msk command. Legal
bits are contained in 0x7FF for the
HD inputs, and 0x7E3 for the SD
inputs, see the chapter on Signal
integrity for explanation on the bit
values. The 2-input cards only
display 2 video monitors.

pri: a prioritized list of inputs, used
when change-over is automatic. The
list can have 1, 2 or 3 entries, or
levels. Manual mode is effectively the
same as automatic mode with one
priority level only, but has its own
command.
0 = from electrical input
1 = from optical input

t1 and t2: change-over doesn't
happen immediately, as a precaution
against glitches and unstable signals.
The timers t1 and t2 let the user
decide how long (in ms) we will cling
on to a missing input before we
consider it gone and move on to the
next pri level, and how long an input
with a higher priority should be
present before we consider it
repaired and switch back,
respectively.

9 Laser safety precautions

These are guidelines to limit hazards from laser exposure. Therefore this note on laser
safety should be read thoroughly.

The lasers emit light at wavelengths from 1270 nm up to 1610 nm. This means that the
human eye cannot see the beam, and the blink reflex cannot protect the eye. (The human
eye can see light between 400 nm to 700 nm).

A laser beam can be harmful to the human eye (depending on laser power and exposure
time). Therefore:

Be careful when connecting / disconnecting fiber pigtails (ends).
Never look directly into the pigtail of the laser/fiber.
Never use microscopes, magnifying glasses or eye loupes to look into a fiber

end.
Use laser safety goggles blocking light at 1310 nm and at 1550 nm

Instruments exist to verify light output power: Power meters, IR-cards etc.
Flashlink features:
All the laser module cards in the Flashlink product range, are Class 1 laser products

according to IEC 825-1 1993, and class I according to 21 CFR 1040.10 when used in
normal operation.

Maximum output power1: 5 mW
Operating wavelengths: > 1270 nm

Max power is for safety analysis only and does not represent device performance.
