PRELIMINARY INFORMATION
Jetson Orin NX Series and Jetson Orin Nano Series DG-10931-001_v1.1 | 52
9.2 HDMI
A standard DP 1.4 or HDMI v2.1 interface is supported. See Figure 9-6 for more details.

Notes:
1. Level shifters required on DDC/HPD. NVIDIA Orin pads are not 5V tolerant and cannot
directly meet HDMI VIL/VIH requirements. HPD level shifter can be non-inverting or
inverting. The HPD level shifter in the reference design is inverting. 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. If EMI/ESD devices are necessary, they must be tuned to minimize the impact to signal
quality, which must meet the timing and electrical requirements of the HDMI specification
for the modes to be supported. See requirements and recommendations in the related
Table 9-5).
3. The DP1_TXx pads are native DP pads and require series AC capacitors (ACCAP) and pull-
-downs must be disabled when Orin
module is off or in sleep mode to meet the HDMI VOFF requirement. The enable to the FET,
enables the pull-downs when the HDMI interface is to be used. Chokes between pull-downs
and FET are optional improvements for HDMI 2.0 operation.
4. See the RS section in Table 9-5 for details.
