Features

Octal 10 Mbits/s Transceiver

s

DSP based.

s

Compatible with

for twisted-pair cable.

s

Half- and full-duplex operations.

s

Autopolarity detection and correction.

s

Adjustable squelch level for extended wire-length

capability (two levels).

s

Interfaces with

interface (MII) or a serial 10 Mbits/s 7-pin interface.

s

On-chip filtering eliminates the need for external fil-

ters.

Octal 100 Mbits/s Transceiver

s

Compatible with

PCS/PMA (clause 24), PMD (clause 25), MII man-

agement, and autonegotiation (clause 28) specifi-

cations.

s

Selectable 5-bit code-group (PDT/PDR interface)

or 4-bit data nibbles (MII interface) input/output.

s

Full- or half-duplex operations.

s

Optional carrier integrity monitor (CIM).

s

Selectable carrier sense signal generation (MCRS)

asserted during either transmission or reception in

half duplex (MCRS asserted during reception only

in full duplex).

s

Adaptive equalization and baseline wander correc-

tion.

s

On-chip filtering eliminates the need for external

filters.

Octal 100 Mbits/s FX Transceiver

s

Compatible with

dard.

s

Reuses existing twisted-pair I/O pins for compatible

fiber-optic transceiver pseudo-ECL (PECL) data.

s

Fiber mode automatically configures port:

— FX mode enable is pin or register selectable

— Disables autonegotiation and 10Base-T.

— Enables 100Base-FX remote fault signaling.

— Disables MLT-3 encoder/decoder.

— Disables scrambler/descrambler.

General

s

Ports individually configurable

s

Autonegotiation and management:

— Fast link pulse (FLP) burst generator.

— Arbitration function.

— Accepts preamble suppression.

— Operates up to 12.5 MHz.

s

Supports the MII station management protocol and

frame format (clause 22): basic and extended reg-

ister set.

s

Supports next page.

s

Provides status signals: receive activity, transmit

activity, full duplex, collision/jabber, link integrity,

and speed indication.

s

Powerdown mode for 10 Mbits/s and 100 Mbits/s

operation.

s

Loopback testing for 10 Mbits/s and 100 Mbits/s

operation.

s

0.25

µm low-power CMOS technology.

s

Single 3.3 V power supply operation.

s

25 MHz XTAL oscillator input or 25 MHz/50 MHz/

125 MHz clock input.

s

Compatible with RMII (standard version) and SMII

(standard version).
