Discrete A/D converters

Three discrete A/D converters with external reference generation and sync slicing
are used for component RGB digitization. The converters can be operated at up
to 30 MSPS.
In addition, the converters black and white reference levels can be adjusted
individually. The black and white reference levels can be adjusted between 0.6 V
to 1.6 V and 1.6 V to 2.6 V respectively, in increments of 10.23 mV (98 distinct
adjustments).
Use the MIL-Lite MdigReference() command to set the black and white reference
levels.

PSG

The Programmable Synchronization Generator (PSG) is responsible for managing
all timing and synchronization signals.

Phase-locked loop

The high-performance, low-jitter phase-locked loop (PLL) uses frequency
synthesis techniques to generate the clock signal, when necessary.
The PLL can use the following sources as a reference:
• The on-board crystal oscillator.
• The horizontal video synchronization signal supplied by the video source
(line-locked mode).
• The clock signal supplied by the video source (to generate a different clock).
When in line-locked mode and accepting a composite video signal, the PLL can
synchronize to either serrated or block vertical synchronization signals.
When the input source supplies a sampling clock that does not require adjustment,
the PLL is bypassed to avoid adding jitter to the supplied clock.
