ADV7611 : Lost DE lock (DE_REGEN_FILTER_LOCKED)

Dear,

 

When I have a 1920x1080@24Hz in input that is correctly displayed, regularly I read DE_REGEN_FILTER_LOCKED to 0 even if VERT_FILTER_LOCKED and TMDS_PLL_LOCKED are set to 1 at the same time.

If I monitor this specific bit it seems that I lost the lock status for at least 2 seconds but I don't see anything on the display (movie is well displayed).

 

On the same product with a ADV7842 front end (software driver is almost similar) I have no problem with this lock status with the same input.

 

The problem seems the same that the one detailed in this post : http://ez.analog.com/message/108772#108772

 

Best regards,

 

Yannick
