Notes:
1. Level shifters required on DDC/HPD. Xavier 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 sections of the “HDMI Interface Signal Routing
Requirements” table (Table 8-5).
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 Xavier 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 in Table 8-5 for details.
5. See reference design for CEC level shifting/blocking circuit.
