DATASHEET

Receive Error

RXER

VO8

This signal is asserted to indicate that an error

was detected somewhere in the frame presently

being transferred from the transceiver.

Note:

This signal is optional in RMII Mode.

Receive

Data 4

(MII Mode)

RXD4

VO8

In Symbol Interface (5B Decoding) mode, this

signal is the MII Receive Data 4 signal, the MSB

of the received 5-bit symbol code-group.

Note:

Unless configured to the Symbol

Interface mode, this pin functions as

RXER.

PHY Address

Configuration

Strap

PHYAD0

VIS

(PD)

Combined with PHYAD1 and PHYAD2, this

configuration strap sets the transceiver’s SMI

address.

See Note 2.1 for more information on

configuration straps.

Note:

Refer to Section 3.7.1, "PHYAD[2:0]:

PHY Address Configuration," on

page 36 for additional information.

VO8

In MII mode, this pin is the receive clock output.

MII (100BASE-TX): 25MHz

MII (10BASE-T): 2.5MHz

PHY Address

Configuration

Strap

PHYAD1

VIS

(PD)

Combined with PHYAD0 and PHYAD2, this

configuration strap sets the transceiver’s SMI
