7 Sync Features

Provision for all Video/TC related signals (VITC, LTC, and Video Sync) is both on a 8-pin Mini-Din
connector (for external connection) and on a 16-pin header (for internal connection). The Video Out
can also serve as VITC output and/or TC burn-in output.
The Mykerinos board supports all standard Video formats such as PAL/NTSC, and all Tri-level HDTV
formats as a reference synchronization source. VITC can only be extracted from standard video
formats. Here are the different possibilities offered by either the Video/TC bracket or breakout cable:

• NTSC/PAL/VITC Video Reference Input + HDTV reference sync source Input

• NTSC/PAL/VITC Video 2 Input or Wordclock I/O

• NTSC/PAL/VITC Video Output

• LTC (SMPTE/EBU) Timecode Input (balanced, nominal 2 Vp-p)

• LTC (SMPTE/EBU) Timecode Output (unbalanced, programmable level)

The breakout cable allows Mykerinos to lock to a video “house sync” or a Wordclock reference, read &
generate VITC and read & generate LTC. This option also adds the capability to "burn" a Time code
"insert" in the video output signal. This interface has provision for one BNC input CVS1In, one BNC
Input/Output CVS2In/WCK, one BNC output CVS Out, one XLR Female for LTC input and one XLR
Male for LTC output.

It is quite similar in functionality to the Video/TC bracket option. The main difference is in the loop
through mode, which is not available with the breakout cable. Therefore the standard recommended
setup is to have JP4 closed on the Mykerinos card to terminate the CVS1In signal with 75 Ohms on
board and to leave open the similar jumper on the Video/TC bracket (to avoid double termination).

7.1 Signal Description

7.1.1 CVS1 IN

This input accepts a composite PAL/NTSC or Tri-level HDTV video signal that can be used by
Mykerinos to lock its audio sampling rate to a video reference. The CVS1 input should be used for the
main “house sync” or "black-burst" reference video signal. It is also possible to use this input as a
VITC source (only standard PAL and NTSC rates).
Note: for proper operation this input should be terminated, with a 75ohm resistor, by closing the
jumper JP4 on Mykerinos when connected to the breakout cable.

7.1.2 CVS2IN / WCKIn&Out

This connector can be used, under software control, in 3 modes: Video 2 IN, Wordclock IN or
Wordclock OUT.
When fed with a video signal it may be used as a secondary VITC source or an alternate video input to
be used for the TC window inserter. It is however not possible to use it as the primary external video
reference signal and requires at all times a "house-sync" signal connected to CVS1IN for proper
operation.

Note: when used as a secondary Video Input with the breakout cable, it should be terminated with a
75ohm resistor by closing the jumper JP5 on Mykerinos.

When software configured as a WCK Input it accepts an external Wordclock reference signal between

0.2 and 5 Vp-p.
When software configured as a WCK Output it provides a 5 V TTL-compatible signal with 100-Ohm
output impedance.

Note: whenever used with a Wordclock signal (either Input or Output), do not terminate (JP5 open) on
Mykerinos and on the Video/TC bracket.

Merging Technologies 9 Mykerinos User Manual

A

7.1.3 CVS OUT

This signal outputs a composite video signal whose source can be software selected to be CVS1IN or
CVS2IN. This signal may additionally carry a VITC and/or a time code "burn-in" video insert
generated by Mykerinos.
Note: CVSOUT provides a monitoring quality video output only and is not intended to be used as a
loopthrough “black burst” output.

7.1.4 LTC IN

LTC IN is a symmetrical input signal. It accepts an external SMPTE/EBU time code signal between 0.2
and 5 Vp-p.

7.1.5 LTC OUT

LTC OUT is an unbalanced output signal. The output voltage level can be software adjusted from 0V
to 2.5V p-p.

9 Mykerinos Modular I/O Daughter cards

One core feature of Mykerinos’ architecture is to break it into two parts: the portion that plugs into the
PCI connector of the PC and the I/O daughter card that contains the physical connectors to the outside
world. This allows for potentially many system applications without committing the design to any
specific I/O configurations.

9.1 ADAT I/O Daughter Card

This I/O daughter card features two sets of Toslink Optical connectors each carrying up to eight
channels of 24-bit Audio in the ADAT compatible format. This provides up to 16 mono channels of
input and 16 channels of output up to 48kHz and up to 8 channels at 96kHz in S/MUX compatible
format. One of the sets can be programmed in software to carry SPDIF (or AES-EBU) formatted
signals instead of ADAT. In this mode, total I/O is limited to 2 + 8 = 10 Digital Audio channels.

The following figure represents the configuration of the Mykerinos bracket when plugged with an
ADAT daughter card.

Merging Technologies 13 Mykerinos User Manual

The optical ADAT daughter card is supplied with two 2-meter optical fiber cables. Other length (up to
10 meter) can be ordered from your authorized Merging dealer.

For long distance optical connections, Merging provides the Onouris long distance system, which
converts the ADAT plastic light-pipe into a signal suitable for glass fiber connection up to 1000 meters.
Cables with various glass fiber lengths can also be supplied.

9.2 MADI I/O Daughter Card (including version II)

The Mykerinos MADI Daughter board is the solution for high I/O channel count applications. It offers
56 channels of 24 bit bi-directional I/O and up to 64 channels in MADI-X (MADI Extended) format. It
can be ordered either in a BNC based coaxial version or an optical duplex SC version. Both versions
are fitted with a standard Wordclock BNC I/O connector, which can be software programmed as a
Wordclock In or Wordclock Out signal. The version II of the MADI daughter card is now fully
multi-board compliant.

9.3 AES-EBU, SDIF, TDIF I/O Daughter Card

The Mykerinos AES-EBU Daughter board offers 24 channels of digital I/O over 12 AES-EBU input
and output pairs. 8 channels feature real-time Sampling Rate Conversion from 32 to 96 kHz, which
may be inserted either in the input or output signal path under software control. Both “single wire” (32
to 96 kHz) and “dual wire” (64 to 192 kHz) modes are supported under software control. Connection is
over three DB-25 connectors (one primary on the daughter card itself, two additional connectors on
separate ribbon cables). This option includes three DB-25 to XLR cables. Special versions with either
SDIF or TDIF format instead of AES-EBU may also be offered.
