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 DisplayPort 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.
