LAN Chipset ATHEROS AR8151L
Package 40pin QFN
Features • The AR8151L 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 AR8151L 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 AR8151L contains an embedded 256 byte Onetime
Program able (OTP) memory (using ondie eFuse
technology) to offer an ultra-low cost solution to the
Ethernet market.
• The AR8151L is compsliant with IEEE 802.3u
specification for 10/100 Mbps Ethernet and IEEE
802.3ab specification for 1000 Mbps Ethernet. The
AR8151L 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 AR8151L GbE controller supports checksum offload
features for IP, TCP, and UDP, lowering CPU utilization
and optimizing network performance.
• The AR8151L also supports advanced power
management functions, including Wake-On- LAN (WOL)
and AMD Magic Packet™.
