Hello,

 

I have some questions about behavior of LLC pin of ADV7180 during reset.

Please see attached file "LLC_waveform_during_reset.PNG".
This is LLC waveform during reset on ADV7180 evaluation board.

 

Question 1:
The LLC waveform seems to be abnormal (very high frequency and unstable) during reset.
Is this correct behavior?

 

Question 2:
Why does LLC output abnormal waveform during reset?

 

Question 3:
Is there any work-around for this behavior?

 

Thank you!
Best regards.
