1) I assume you have 100nF caps in the RGB lines as shown in the reference schematic.2) how are you programming 0xC3 and 0xC4. They control which analog input goes to which ADC.

Hello, Looks like the ADV7524A can only support RGB imagers on the rising and falling edge (DDR.) Can it support RGB on just either edge? Thanks in advance.Scott
View ArticleRe: Can ADV7524A support RGB imager input without DDR?
Hi Scott, Unfortunately, ADV7524A is still under NDA (all the portable TXs are) so we can't discuss it on the forum. You'll need to contact ADI Sales. Dave
