ADV7441A detects NTSC composite input video as PAL

Hello All,


We are using ADV7441A chip in our customized TI's DM6467 processor based board. We have given composite NTSC video input with 2-3 different video sources from different vendors like Phillips, Sony, appo etc. With the 20-25 iterations it detects NTSC resolution but sometimes randomly it detects PAL resolution. We have tried this issue with different video input cables as well.


Please help us to resolve this issue.
