Signal Type Definitions

The signals of the 82575 controller are electrically defined as follows:

Definition

DC specification

Input

Standard input only digital signal.

See Table 9

Output

Standard output only digital signal.

See Table 9

Tri-state

Bi-directional three-state digital input/

output signal.

See Table 9

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.

See Table 10

Analog

PCI Express*, SERDES, or PHY analog

signal.

See Table 10

Power

Power connection, voltage reference, or

other reference connection.

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.
