ADV7513 - Queries on HPD Input

Question asked by on Dec 3, 2015

I have the following queries regarding ADV7513 HPD (Hot Plug Detect) input.


1. Is HPD input edge triggered or level triggered?


2. If it is level triggered, what is the duration for which the HPD should be asserted to indicate the connection to the sink?


3. If it is edge triggered, can a spike of voltage greater that 1.3V (minimum high level input voltage for HPD) cause the HPD to be asserted?
