    hi, all,
    
 
       in our video capture and play project,we used ADV7180 and SAA7128 for video decoder and encoder,respectively.in 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.

        hi,dave,
        
 
            i know that ADV7392/7393 can  satisfy my design requirement,but,in that case,i must to use 2pcs adv7392/7393 in this project.because,i  need a video encoder that have a full niterface for analog video output,in other words,i want the video encoder can output YUV ,CVBS and S-Video at the same time.
        
 
           and i want to use odd chip plan.adv7172/7173 and adv7392/7393  have six DACs.but, adv7172/7173 is appear on the market in 2001,so i am worry about it`s stop production in future years.
