Can the ADV7403 supports more than two RGB inputs?
The ADV7403 can support up to three RGB inputs without any external circuitry – 2 with embedded syncs (with the embedded syncs connected to SOG and SOY) and 1 with non embedded syncs (HS and VS connected to the HS_IN and VS_IN pins).
The ADV7403 can support up to four RGB inputs with external circuitry – 2 with embedded syncs (with the embedded syncs connected to SOG and SOY) and 2 with non embedded syncs (HS1 and HS2 connected to a mux and with the mux output connected to HS_IN and similar for VS1 and VS2).
Does the same go for YPbPr with SOY?
I have an application that requires 4 YPbPr inputs, all with SOY. Would the best option be to use a couple of AD8183 or similar to mux the 4 inputs down to 2? Which input channels would be best to use?
