Hi,

 

My customer is designing with ADV7511W for her automotive rear view camera.

I've tried lots of register settings, but couldn't get normal video output at her monitor.

Monitor showed only green display and it detected video input as 720p@60Hz.

 

Mainly I used below register setting.

Can somebody check whether this setting has any problem ?

 

Input : 720p@60Hz, YCbCr 16bits, 4:2:2 format, Seperate Sync, Not using HDCP encryption

           D[23:16] : CbCr 8bits, D[15:8] : Y 8bits, Evenly Distributed, Style 1, Input ID = 1
