Hi,
I have question about DP1_HPD(HP_DET) of the Jetson Orin NX.
I read “Figure9-8 and Table9-6” of Jetson_Orin_NX_Series_and_Orin_Nano_Series_Design_Guide_DG-10931-001_v1.0.pdf.

HP_DET of Table9-6 is required 100kΩ series resistor. 100kΩ to GND on connector side → 100pF/12pF caps to GND.
HP_DET of Figure9-8 have not 100kΩ series resistor. 100kΩ to GND on connector side and one cap to GND.

Which is correct description?

If Table9-6 is correct, is the below connecting OK?

Level shift <--------100kΩ----------①-------②-------③--------④-------HP_DET(HDMI connector side)

①100kΩ to GND
②100pF to GND
③12pF to GND
④ESD to GND

The figure 9-8 will be updated, thanks. You can refer to below design from Xavier NX for detail.
