AR8032 Integrated 10/100 Fast Ethernet Transceiver

Manufactured in a standard CMOS process, the

AR8032 is packaged in a 32-pin QFN, featuring

a small body size of 5 x 5mm.

General Description

The Atheros AR8032 Fast Ethernet transceiver

is a highly integrated physical layer device that

transmits and receives high-speed data over

standard category 5 (CAT 5) unshielded

twisted pair cable.

The AR8032 is compliant with 100 BASE-TX

and 10 BASE-T IEEE 802.3 standards. The

AR8032 device uses advanced mixed-signal

processing technology and integrates functions

such as adaptive equalization, and timing

recovery to deliver substantial power savings

and operation in noisy environments.

Features

■ 10/100 BASE-T IEEE 802.3 compliant

■ Supports MII/RMII interface

■ Low power modes with internal automatic

DSP power saving scheme

■ Fully integrated digital adaptive equalizers

All digital baseline wander correction

■ Supports external 25 MHz clock source in

MII mode

■ Supports external 50 MHz clock source in

The AR8032 device supports the Media

Independent Interface (MII) and Reduced

Media Independent Interface (RMII) for direct

connection to a Fast Ethernet-capable MAC.

RMII mode

■ Automatic speed downshift mode

■ Automatic MDI/MDIX crossover

■ Automatic polarity correction

■ Loopback modes for diagnostics

■ IEEE 802.3u compliant Auto-Negotiation

■ Software programmable LED modes

■ Cable Diagnostic Test (CDT)

The AR8032 supports the Atheros Cable

Diagnostic Test (CDT) feature, which uses Time

Domain Reflectometry (TDR) technology to

quickly and remotely identify potential cable

malfunctions without deploying field support

personnel or bringing down the network. The

AR8032 solution detects and reports issues

such as PHY malfunctions, bad/marginal cable

or patch cord segments or connectors, thus

significantly reducing installation time, cable

debug efforts, and overall network support

cost.

■ Requires only one 3.3V power supply

■ 32-pin QFN 5mm x 5 mm package
