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 burnin 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.
7.1.2 WCKIO (Old CVS2In) This connector can be used, under software control, in 2 modes: Wordclock IN or Wordclock OUT. 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 22-Ohm output impedance.

7.3 Video/TC Header Pin-out descriptions (JP2) The pins on the Video/TC header are as described below: Spare 2 500mA fused +5v ASC Out ATC Out RXD TXD GND Spare 1 CVS2/WCLK In & Out GND CVS1 In CVS Out LTC In LTC Out SCL SDA PCB Component side Figure 5 - Video/TC Header Pin-out When the Video/TC Header is used, be sure to not terminate twice the CVS1IN input. Use only either the termination on the Mykerinos board (JP4) or this provided on the Video/TC Header.
8 Monitoring Headphone Features (J3) The monitoring output is based on a stereo 96kHz / 24 bit D/A (unbalanced). The output level is software controlled. Mykerinos revision D and above feature 2 new jumpers JP6 and JP7 on the left and right channels respectively. Opening these jumpers results in a 12 dB gain reduction on each monitoring channel. 8.1 Monitoring output characteristics The first graph shows the frequency response & the THD+N @ 48kHz and the second graph shows the Noise floor FFT @ 48kHz .
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.
9.1.1 Optical I/O configuration The following tables resume the I/O formats available in each mode. These formats are software selectable into Pyramix. (A = Optical A / B = Optical B) 9.1.1.
9.2 MADI I/O Daughter Cards - 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.

9.3.1 AES-EBU without SRC • • 24 channels of 24-bit digital input over 12 AES EBU pairs. 24 channels of 24-bit digital output over 12 AES EBU pairs. 9.3.2 AES-EBU with SRC on 8 channels • • • 24 channels of 24-bit digital input over 12 AES EBU pairs. 24 channels of 24-bit digital output over 12 AES EBU pairs. 8 (out of 24) channels feature SRC (Sampling Rate Converter) up to 96 kHz either on input or on output. 9.3.
9.4 DUAL Daughter Card The Dual DC is the most cost-effective I/O daughter card for Pyramix. It is an ideal I/O solution for mixed analog/digital requirements, as encountered in Broadcast production, and Video/Film post-production environments. It allows the direct connecting of up to two electrodynamics or condenser microphones, typically for quick and easy voice-over recording. 9.4.
9.4.2 Front connector This DB25 connector is for the DUAL ANALOG I/O breakout cable, as shown in the following drawing. ANALOG IN 1 ANALOG IN 2 ANALOG IN 3 ANALOG IN 4 ANALOG I/O ANALOG OUT 1 ANALOG OUT 2 ANALOG OUT 3 ANALOG OUT 4 ANALOG IN 1 - 4 Any professional level balanced audio output can be connected to the analog line inputs of the DUAL Daughter card. Input levels are selectable from consumer level (–10 dBV) up to professional level (+4 dBu).
