I have a requirement for a wideband PAL input in square pixel mode (7.2MHz max signal). Previously I used the ADV7188 but the Standard definition (SD) decoders attenuate any signal above 6.25MHz.
I am now using the ADV7403 and routing the CVBS video into AIN6 (Y in component input). This routes the video through the Component Processor (CP) path which neatly passes the 7.2MHz signal.
But I need to switch a second CVBS input through this CP path. I tried setting up the manual multiplexing to input AIN10 but I could not get it to work. I also tried a few other AIN inputs with the same result.
Can I route another input (other than AIN6) through the CP?
