Hi all.

We are using the HDMI port of ADV7842.
We implemented the "2.2.8 TMDS PLL Lock" described in "ADV7842 Recommended Settings Rev2.0_241013.pdf“,


but it does not work sometimes.
We found out that putting some wait time after TMDS reset improves this issue.
Please tell me if this wait time is nessesary? What is the wait time?
Actually, The datasheet and hardware user guide does not say anything about it.


Best regards.
