Hi,
I'm working with ADV7393 and AD725 for RGB to Y/C video output.
During the design phase i thought the sync pulse is comes only on Green(G) color input signal.
So i stripped the sync pulse by using the AD8062 only on green color and feed to AD725 chip, without sync stripping of Red and Blue.
Hence the Y/C video output color is distorted (as a blueish).
If i control the ADV7393 0x02[4] register
as enabled, the output comes blueish and if i disabled, the total image/video is distorted.
So how to preserve the original image/video (without color deviation) in this design?
Thanks,
Siva
I am also facing the same issue. I am using ADV7393 IC and its output is connected to AD725.
i stripped the sync pulse by using the AD8062 on green, blue and red color and feed to AD725 chip.
I fed green signal to EL1881 sync separator IC from ADV7393 IC to separate the sync signal and fed SYNC output from this IC to HSYNC pin of AD725.
But the Y/C video output color is distorted (as a blueish, greenish,grey).
