The HPD signal comes from the HDMI or DP connector. This is
a low frequency, 0V to 5V (HDMI) or 3.6V (DP) input signal at
the connector.
The HPD input at the mux is 3.6V max, so HDMI HPD must be
shifted down from 5V before it is passed to the mux.
Differential input from GMCH PCIE outputs. IN_0+ makes a
differential pair with IN_0-.
Differential input from GMCH PCIE outputs. IN_0- makes a dif-
ferential pair with IN_0+.
Differential input from GMCH PCIE outputs. IN_1+ makes a
differential pair with IN_1-.
Differential input from GMCH PCIE outputs. IN_1- makes a dif-
ferential pair with IN_1+.
Differential input from GMCH PCIE outputs. IN_2+ makes a
differential pair with IN_2-.
Differential input from GMCH PCIE outputs. IN_2- makes a dif-
ferential pair with IN_2+.
Differential input from GMCH PCIE outputs. IN_3+ makes a
differential pair with IN_3-.
Differential input from GMCH PCIE outputs. IN_3- makes a dif-
ferential pair with IN_3+.
The latch gate is controlled by LE. 3.6V tolerant, low-voltage,
single-ended input.
Pass-through output from AUX+ input when SEL = 1. Pass-
through output from Rx0+ input when SEL = 0.
Pass-through output from AUX- input when SEL = 1. Pass-
through output from Rx0- input when SEL = 0.
Differential input from PCIE connector or device. Rx0+ makes a
differential pair with Rx0-. Rx0+ is passed through to the OUT+
pin when SEL = 0.
Differential input from PCIE connector or device. Rx0- makes a
differential pair with Rx0+. Rx0- is passed through to the OUT-
pin when SEL = 0.
Differential input from PCIE connector or device. Rx1+ makes a
differential pair with Rx1-. Rx1+ is passed through to the X+ pin
when SEL = 0.
