Doubt about ADV7188 and output timing

Hi all,

 

I am working with a ADV7188 to digitalized PAL signal to ITU-R BT.656. This last signal is serialized with a chip of Gennum Co. I am having some problems with the communication between the 2 parts, and, specifically, with ITU timing issues. The Gennum chips works with H:V:F timing (TRS words embedded) and CEA-861 (sync signals provided externally). With the CEA timing, the Field signal is not useful because Gennum chip expects a Data Enable instead of the Field signal. So I am trying to use the embedded format but I don't know well how can I get this timing (register configuration) and if it is possible to get.

 

Thanks in advance.

 

Regards.
