I want to connect ADV7619 to my encoder chip with 4K input video. The input port of the encoder chip is 16bit, 148.5MHZ, BT.1120, dual-edge sampling .
Does ADV7619 support BT.1120&148.5MHz dual-edge output ?
The limit is the max output clock rate. The ADV7619 LLC limit is 170MHz. This same limit applies to the data lines. So even if you did 4K output in DDR mode on 16 bit bus, the clock would be OK but the data lines would be 340MHz. This is why you need to use the double wide bus output instead. So ADV7619 cannot run DDR mode with an LLC clock of 148.5MHz.4K bypasses the CP.
Did you check these threads? I believe this would help you
Thanks for your answers .
But the 3 questions don't solve my problem. I want to know whether the ADV7619 support dual-edge output ?
The second question has refered to 4Kx2K signals do not go through the CP . Is it means 4k pixel output formatting doesn't support 16bit bt.1120 ?
