I am looking at the analog parts of the schematic and haven't found
anything yet.
I had some questions about the design. I have answered some by
downloading some data sheets. But still have some remaining questions
about the video DACs.
It seems that we have a very expensive solution for this so I was
wondering about the required specs.
1. What is our max clock rate for the DACs?
2. What is the bandwidth required for the video out buffers.
Note that in theory if we use shunt peaked video out buffers that #2
would be twice #1 for analog video but it would be normal to have an
additional frequency margin.
There is digital so you would probably want the video out signal to have
the 3rd harmonic for good rise time. If so, you need 6x +/- and TV
video buffers wouldn't do the job.
I couldn't find a video SRAM in the design? I would want this as a
feature in the final board and would prefer 12 bit per color.
