3.0 Signal Descriptions and Pinout List
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.
3.1 Signal Type Definitions
The signals of the 82575EB are electrically defined as follows:
Name
I
O
TS
OD
A
P
Definition
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
PCI Express*, SERDES, or PHY analog signal.
Power
Power connection, voltage reference, or other
reference connection.
