I am interested in using the ADV7800+RAM in a glueless frame synchronization application with output port going directly to an encoder IC. I want the output encoder synchronized with an external video source (genlock in) which I'll be using a cheaper decoder IC for, to generate LLC and syncs.
While ADV7800 page claims frame synchronizer capabilities with its internal RAM, I'm having trouble figuring out how I would achieve genlocked output using a secondary video source. All I see in the ADV7800 docs is that I can use the ADV7800's own LLC as the output clock, or a fixed frequency definable in I2C registers.
Any clues as to whether my application will be possible with this chip?
