Pin #

Description

TD-, TD+

I/O

14, 15

Differential common driver transmit output (PMD Output Pair).

These differential outputs are automatically configured to either

10BASE-T or 100BASE-TX signaling.

In Auto-MDIX mode of operation, this pair can be used as the Re-

ceive Input pair.

These pins require 3.3V bias for operation.

RD-, RD+

I/O

11, 12

Differential receive input (PMD Input Pair). These differential in-

puts are automatically configured to accept either 100BASE-TX

or 10BASE-T signaling.

In Auto-MDIX mode of operation, this pair can be used as the

Transmit Output pair.

These pins require 3.3V bias for operation.

Description

RBIAS

I

20

Bias Resistor Connection. A 4.87 k

Ω 1% resistor should be con-

nected from RBIAS to GND.

PFBOUT

O

19

Power Feedback Output. Parallel caps, 10

µ F (Tantalum pre-

ferred) and 0.1

µF, should be placed close to the PFBOUT. Con-

nect this pin to PFBIN1 (pin 16) and PFBIN2 (pin 30). See

Section 5.4 for proper placement pin.

PFBIN1

PFBIN2

I16

30

Power Feedback Input. These pins are fed with power from

PFBOUT pin. A small capacitor of 0.1

µF should be connected

close to each pin.

Note: Do not supply power to these pins other than from

PFBOUT.
