AD725 wrong color on output

Hi,

 

I'm working with AD725 for a while now and I have a problem with color outputs.

I displayed only Red images, then Green, then BLUE.

Blue appears to be blue, Red is Magenta and Green is Cyan.

So it seems that blue is always displayed.

I tested and verified many times everything on my design but I can't find where the problem come from. When I displayed one color images, RGB inputs are at correct levels for example when I have datas on RIN (between 800mV and 1.5V), GIN and BIN are at 800 mV (measure on pin).

 

I noticed this problem on 3 different cards !

Any idea ?
