Note:
1. A Level shifter is required on HPD to avoid the pin from being driven when the module is off. The level shifter must be non-
inverting (preserve the polarity of the HPD signal from the display ).
2. Pull-up/down only required for DP – not for eDP.
3. If EMI devices are necessary, they must be tuned to minimize the impact to signal quality, which must meet the timing &
electrical requirements of the Display Port specification for the modes to be supported. Any ESD solution must also maintain
signal integrity & meet the DisplayPort requirements for the modes to be supported.
