No video output from ADV7403 with analog RGsB (sync on green) configuration

Category: Hardware
Product Number: ADV7403

Hello,

We are trying to bring up analog RGB with sync on green to ITU-R.BT656 on a custom board. While the input is locked and valid video is recognized by the CP (from STATUS_2 register, addr: 0x12), the digital output does not contain ITU-R.BT656 data. 

We have connected RGB to AIN1,2,3 and green also to SOG pin as given in the example schematic in the datasheet. Different combinations of the configurations were tried (script used is 625I SCART RGB IN In Thru CP YPrPb 2X1 10 Bit 422 Out, with changes for manual muxing). We have also attempted to connect composite and used the script provided by ADI for autodetection (through AIN10) but in that case the SDP is free-running and has not recognized the video. 

Please find the configurations below (addr, data):
