hi, all,

   in our video capture and play project,we used ADV7180 and SAA7128 for video decoder and encoder, addition, we must use the SFL function witch is output from ADV7180.unfottunately,when we connect SFL pin from ADV7180 to SAA7128`s RTCO pin,video which output from SAA728 is not normal.By contrast,when we do not use SFL function,the output video is normal.So, we are consider the SFL signer and RTCO signer are incompatible.

But,our circuit board had been producted, so,can you give our an effective solution.thanks.
