I read in all of these datasheets that the AD723,AD725, and AD725 all require interlaced inputs. If I want to feed a pc's vga output into one of these IC's, would these still convert the RGB to composite? Are there other solutions from Analog Devices that are RGB-to-NTSC Encoders that do not require an interlaced input? The AD723,AD725, and AD725 all looked like good solutions because they can be hardware configured and do not require some configuration scripts over I2C.
Any help on this would be great.
Thank you,

Hi Scott,
Ok.. the PCIE to NTSC was the part I was missing-- it's specifc to encoded analog NTSC or is it digital? That seems like a strange part. If the XGA is just digital data, wouldn't any arbitrary PCIE bridge part do the trick? I imagine some buffering is all you'd need.
We don't have anything that we can discuss on the forum but a scaler part for what you want doesn't seem like the right solution anyway.
