ADV7612 Detecting Fractional Frame Rates

Hello,

 

We are facing one issue with ADV7612 in detecting fractional frame rates properly. We are using TMDS_FREQFRAC register to figure out whether the input fed is of fractional frequency or not but, this approach is giving random results with different video sources.

 

Did anybody face the same issue with ADV7612?

 

Is there any mechanism with which we can accurately determine the frame rate of input video in ADV7612?

 

Thanks & Regards,

Shubham
