7.2.2 HDMI
A standard HDMI V2.0 interface is supported. These share the same set of interface pins, so
either DisplayPort or HDMI can be supported natively.

Notes:
1. Level shifters required on DDC/HPD. NVIDIA
®
Tegra
®
X2 pads are not 5V tolerant and cannot directly
meet HDMI VIL/VIH requirements. HPD level shifter can be non-inverting or inverting. HPD level
shifter on the Jetson TX2 NX Developer Kit is inverting.
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 sections of Table 7-9.
3. The DP1_TXx pads are native DP pads and require series AC capacitors (ACCAP) and pull-downs (RPD)
to be HDMI compliant. The 499Ω, 1% pull-downs must be disabled when Jetson TX2 NX 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. Series resistors RS are required. See the RS section of Table 7-9 for details.
5. See reference design for CEC level shifting/blocking circuit.
