for my drone I want to develop a custom Jetson carrier board with minimal required interfaces. For quick debugging I would like to add an HDMI port on the PCB. However, I’m not familiar with HDMI and I found some contradictions between guides.
In most guides it’s written the impedance of the trace should be 100 Ohm. I found some pretty easy schematics examples
However in the Jetson Nano design guide there more required elements as these capacitors and Rs resistors, which I do not completely understand the purpose…
At the end there is this figure, which tell us to have 500 Ohm impedance traces where all segments should be 100 Ohm :/
I can blindly reproduce the carrier board but I would like to understand better what I’m going to do.
Thx in advance!
