Hot Plug Detect
The SN75DP139 has a built in level shifter for the HPD outputs. The output voltage level of the HPD pin is
defined by the voltage level of the VCC pin. The HPD input or HPD_SINK side has 130kohm of pull down
resistor integrated.
The logic of the HPD_SOURCE output always follows the logic state of the HPD_SINK input based on the
HPDINV pin logic, regardless of whether the device is in Active or Low Power Mode
