PEHPSDA

PCI Express* Hot-Plug SMBus Data: Provides PCI Express* hot-

plug support via a dedicated SMBus interface. Requires an external 

general purpose input/output (GPIO) expansion device on the 

platform.

DMI2 Transmit Data Output

QPI{0/1}_CLKRX_DN/DP

Reference Clock Differential Input. These pins provide the PLL 

reference clock differential input. The Intel QPI forward clock 

frequency is half the Intel QPI data rate.

QPI{0/1}_CLKTX_DN/DP

Reference Clock Differential Output. These pins provide the PLL 

reference clock differential input. The Intel QPI forward clock 

frequency is half the Intel QPI data rate.

QPI{0/1}_DRX_DN/DP[19:00]

Intel QPI Receive data input.

QPI{0/1}_DTX_DN/DP[19:00]

Intel QPI Transmit data output.

QPI_RBIAS

This input is used to control Intel QPI bias currents. QPI_RBIAS is 

required to be connected as if the link is being used even when 

Intel QPI is not used. 

QPI_RBIAS_SENSE

Provides dedicated bias resistor sensing to minimize the voltage 

drop caused by packaging and platform effects. 

QPI_RBIAS_SENSE is required to be connected as if the link is 

being used even when Intel QPI is not used. 

QPI_VREF_CAP

Intel QPI voltage reference used to measure the actual output 

voltage and comparing it to the assumed voltage.
