AR8229/AR8228 Seven-Port Fast Ethernet Switch
General Description
The AR8229/AR8228 is a highly integrated
three-Giga MAC plus Five-port Fast Ethernet
switch with non-blocking switch fabric, a high-
performance lookup unit with 1024 MAC
address, 4096 VLAN table, 32 ACL rule table
and a four-traffic class Quality of Service (QoS)
engine. The AR8229/AR8228 has the flexibility
to support various networking applications.
The AR8229/AR8228 support many offload
function to increase the system performance.
The AR8229/AR8228 is designed for cost
sensitive switch applications in wireless AP
router, home gateway, and xDSL/PON/cable
modem platform. The Fast Ethernet in the
AR8229/AR8228 complies fully with IEEE
802.3 standards. The AR8229/AR8228
implements power saving techniques to
facilitate low power consumption. The
AR8229/AR8228 is designed to work in all
environments. True Plug-n-Play is supported
with Auto-Crossover, Auto Polarity, and Auto-
Negotiation in PHYs.
