4 Introduction
This document presents and describes the third generation Merging hardware/software solution, a PCI based, high performance, cost effective audio processing card named MYKERINOS.
5 Mykerinos Features Overview
Mykerinos is Merging's answer to create a leading edge high performance audio processing card solution. It builds upon over 6 years of experience designing and manufacturing PC based Audio Cards and incorporates hundreds of users feedbacks into a compact third generation flexible solution. Here is a quick summary of features:
• PCI V2.1 compliant. Supports both 5 Volts and 3.3 Volts PCI environments

• Support for all sampling rates from 32 kHz up to 384 kHz
• Open Plug-In (all C-code) architecture supporting Surround-sound and DVD formats
• Highly flexible modular I/O architecture can be tailored to user's needs by the use of dedicated
daughter boards. This I/O modularity offers a unique opportunity to meet a wide range of market requirements
• Current Audio I/O daughter card options include ADAT - S/PDIF, MADI, AES/EBU, TDIF,
SDIF and DUAL
• On board Sync Connector, which includes Video Sync I/O ready for HDTV, VITC reader and
generator, LTC reader and generator and built-in time code insertion into Video window.
• 2 channel 24 bit 96 kHz on-board monitoring output
• Very high performance card capable of high track playback (up to 64 tracks) and vast I/O
capabilities (up to 64 channels)

The Mykerinos board is based on the Philips Trimedia TM-1300 Chip and its associated SDRAM running at 144 MHz. The other peripherals are:
• 1 FPGA (Field Programmable Gate Array), used to manage the control signals
• 1 Timecode reader – generator (LTC and VITC)
• 1 Video PLL, used to lock to any incoming Video reference such as black-burst PAL, NTSC or
Tri-level HDTV
• 1 stereo 24 bit 96kHz D/A for onboard audio monitoring.
Up to 64 audio channels are conveyed over the Trimedia high-speed “Video IN” and “Video OUT” buses through connector J4 to/from the specific I/O daughter card.
6.2 Mykerinos On-Board Connectors and Jumpers
The connectors implemented on the Mykerinos board are as follows:
• JP1 - header 1x2, Reserved.
• JP2 - Video/TC connector 8x2, offering the same functionalities as J2 but for internal
connection
• JP3 - header 1x2, used to connect internally a Video Reference Sync (in lieu of CVS1IN
signal)
• J2 - 1 mini Din 8 pins, used to transfer Video and Timecode signals
• J3 - 1 stereo headphone monitoring output 3.5mm mini-jack connector
• J4 - 1 mezzanine connector 32x2, used to connect I/O daughter cards
• JP4 - 75ohm termination for CVS1IN (input from J2, JP2 or JP3)
• JP5 - 75ohm termination for CVS2IN (input from J2 or JP2)
• JP6 - monitoring gain attenuation (-12dB when open) for the left channel
• JP7 - monitoring gain attenuation (-12dB when open) for the right channel

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.
