SPG-1801
Sync Pulse Generator
The Densité Series SPG-1801 is a sync pulse generator card. It accepts an external reference input or a digital universal reference signal (URS) from the frame reference module REF-1801, if present. It features two fully independent outputs, with user selectable output format (blackburst, tri-level sync, DARS, Word Clock) and user configurable pixel by pixel output timing adjustment. The SPG-1801 can lock on a blackburst or a tri-level sync signal. The output signal can be video (blackburst, tri-level sync) or audio (Word Clock, DARS). In the case of an audio output, the SPG-1801 can also lock on an external DARS or Word Clock.
