I am looking to use one of your chips to output RGB and Composite sync at 1280x1024 60hz, I was looking at the ADV7340, but could not find that timing output. Can someone tell me if this format is supported or if there is another chip that will?
The ADV734x products are primarily intended for analog component output for standard TV modes (480i, 480p, 720p, 1080i).
I'm not sure what you mean by composite sync but I'm guessing ADV734x is not a good fit. What standard and resolution are you trying to output?
