Hi !


Our customer are using ADV7181D.

And they are testing at their own but sometime their system detect ADV7181D is not locking CVBS.

So my question are these.



When ADV7181D cancel ANALOG input lock, IN_LOCK turns to "0".

What is the threshold to unlock.

Maybe my question is almost same to this but the device is different so please answer to my question too.

[ADV7180] Details of the condition (threshold) of the LOST_LOCK and IN_LOCK bits. 


Best regards
