Table 6-5. PCI Express* Miscellaneous Signals
Signal Name Description
PE_RBIAS This input is used to control PCI Express* bias currents. A 50 ohm
1% tolerance resistor must be connected from this land to VSS by
the platform. PE_RBIAS is required to be connected as if the link is
being used even when PCIe* is not used. Refer to the Platform
Design Guide (PDG) for further details.
PE_RBIAS_SENSE Provides dedicated bias resistor sensing to minimize the voltage
drop caused by packaging and platform effects. PE_RBIAS_SENSE
is required to be connected as if the link is being used even when
PCIe* is not used. Refer to the Platform Design Guide (PDG) for
further details.
PE_VREF_CAP PCI Express* voltage reference used to measure the actual output
voltage and comparing it to the assumed voltage. A 0.01uF
capacitor must be connected from this land to VSS.
PEHPSCL PCI Express* Hot-Plug SMBus Clock: Provides PCI Express* hot-
plug support via a dedicated SMBus interface. Requires an external
general purpose input/output (GPIO) expansion device on the
platform.
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.
