Hi,
I am working on a project using HD3SS215 and TMDS181 chips.
Let's take a look at the block diagram below:image.png
The HPD signal have to go through many chips to go from Source side to Sink side.
Do we need any further pull-up and pull-down resistor for this circuit?
Thanks and best regards,
Chau
