HDMI Routing Guidelines

This section describes the HDMI routing guidelines for the Orin module.

Notes:
1. RPD pad must be on the main trace. RPD and ACCAP must be on same layer.
2.
FET are chokes between pull-downs and FET are optional improvements for HDMI 2.0
operation.
3. The trace after the main route via should be routed on the top or bottom layer of the PCB,
and either with 100 ohm differential impedance, or as uncoupled 50 ohm SE traces.
4. See the RS section in Table 9-5 for details.
