Hello

     I am having issues with ADV7619 receiver which can be reproduced by plunging-unplugging the HDMI receiver cable several time.

But some times the receiver also shows same issue on power up. When the issue is there , the output DE is one clock cycle early then outut data, so that first data sample is a garbage.

 

Details of the issue

 

 

  1. Output when working

 

DE    ________________------------------------------------------------------------------__________

 

Data   …. Xxxxxx          | first data, second data, ………,........last data|...xxxxxxxxxx…………….

 

 

2.     Output when not  working

 

DE    ________________------------------------------------------------------------------__________

 

Data   …. ......Xxxxxx   |xxxxxxxxx,first data, second data, ...............,last data|xxxxxxxxxxx…………….

 

Please let me know if anybody seen this issue or if any possible solution is possible .
