ADV7181C in 625i 4x1 mode

Hi,

 

I need to acquire RGsB PAL in 4x1 mode (54MHz sampling frequency and 720x576 output resolution).

My requirements are :

R on Ain5

G on Ain6 and SOG/SOY

B on Ain4

4:4:4 Output in DDR12bit with FVH syncs

 

I used adi scripts to begin and made some changes for my application.

 

The LLC clock frequency is 27 MHz instead of 13,5MHz and a pixel on two seems to be dark.

 

An idea ?

Regards.
