ATHEROS AR8151

Package

48pin QFN

 

 

Features

• The AR8151 is the fifth generation Gigabit Ethernet

 

(GbE) controller solution from Atheros. It is an ultra-high

 

performance, ultralow cost, and ultra-low power fully

 

integrated 10/100/1000 Mbps NIC/LOM Ethernet

 

controller perfectly suited for both PC and embedded

 

applications.

 

• The AR8151 combines a 10/100/1000BASE-T GbE

 

media access controller (MAC), a triplespeed Ethernet

 

physical layer transceiver (PHY), a PCI Express bus

 

interface, and a 25 MHz shared-source clock input and

 

the AR8151 contains an embedded 256 byte Onetime

 

Programable (OTP) memory (using on-die eFuse

 

technology).

 

• The AR8151 is compliant with IEEE 802.3u specification

 

for 10/100 Mbps Ethernet and IEEE 802.3ab

 

specification for 1000 Mbps Ethernet. The AR8151

 

device combines pulse shaping, Tx/Rx PCS, echo

 

canceller, NEXT canceller, equalizer, decoder, and timing

 

recovery functions to deliver robust signal performance in

 

noisy environments

 

• The AR8151 GbE controller supports checksum offload

 

features for IP, TCP, and UDP, lowering CPU utilization

 

and optimizing network performance.
