Notes
:
1.
The load switch circuit shown is intended to remove power to the HDMI connector and related
circuitry to avoid backdrive on signals to the module. Other mechanisms may be used but
must prevent module pins being driven when the module is off.
2.
Level shifters required on DDC/HPD. Jetson AGX Xavier pads are not 5V tolerant and cannot
directly meet HDMI VIL/VIH requirements. HPD level shifter can be non-inverting or inverting.
3.
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. ee requirements and recommendations in the related sections of
4.
The HDMI_DP_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
SoC is off 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 required for
Standard Technology designs and recommended for HDI designs.
5.
Series resistors RS are required. See the RS section of Table 9-6 for details.
