What is purpose of Test4 pin in ADV7842?
Datasheet says, It should be tied to ground.
However, I left it floated by mistake.
What does this pin do?
Currently, I can't receive HDMI at all. Is this relevant to this pin?
TMDS_CLK_A_RAW shows that it couldn't detect clock switching.
ClockData Termination is applied via registers, and I can verify clock & data swing.
But, I'm not confident with TMDS level from ADV7511.
It is only about 500mVpp from 3.3V as common.
Any suggestion would be pleased.
Thank you in advance.
