Notes:
1. Level shifter required on DP0_HPD to avoid the pin from being driven when Jetson Orin NX is
off. The level shifter must be non-inverting (preserve the polarity of the HPD signal from the
display). The reference design uses a BJT level shifter, and a resistor divider is needed. See
the reference design if a similar approach will be used.
2. Load Switch enable is from powergood pin of main 3.3V supply.
