Signal Descriptions
The targeted signal names are subject to change without notice. Verify with your local
Intel sales office that you have the latest information before finalizing a design.
Signal Type Definitions
The signals of the controller are electrically defined as follows:
PCI Express Interface
Name
A(O)
PERn[3:0]
PERp[3:0]
PETn[3:0]
PETp[3:0]
A(I)
OD
TS
Symbol
O
A
P
I
Input
Standard input only digital signal.
Output
Standard output only digital signal.
Tri-state
Bi-directional three-state digital input/output signal.
Open Drain
Wired-OR with other agents.
The signaling agent asserts the OD signal, but the signal is returned to the inactive state by a
weak pull-up resistor. The pull-up resistor may require two or three clock periods to fully
restore the signal to the de-asserted state.
Analog
PCIe*, SERDES, or, PHY analog signal.
Analog-Input
Standard input only analog signal.
Analog-Output
Standard output only analog signal.
Power
Power connection, voltage reference, or other reference connection.
Type
A(O)
A(I)
High Speed Serial Receive Data
These signals connect to corresponding PETn and PETp signals on a system
motherboard or a PCI Express connector. Series AC coupling capacitors are
required at the transmitter end. The PCI Express differential inputs are clocked at
2.5 Gb/s.
High Speed Serial Transmit Data
These signals connect to corresponding PERn and PERp signals on a system
motherboard or a PCI Express connector. Series AC coupling capacitors are
required at the 82571EB/82572EI controller end. The PCI Express differential
outputs are clocked at 2.5 Gb/s.
