Datasheet for Qualcomm Atheros AR8229

7-Port Low-power Managed Hybrid Switch Supports Industrial Temperatures

AR8228/AR8229 Product Overview
The AR8228/AR8229 devices contain five full-duplex 10/100Base-T Ethernet transceivers, each of which performs all of the physical layer interface functions for 10Base-T Ethernet over Category 3, 4, or 5 unshielded twisted-pair (UTP) cable and 100Base-T Ethernet over Category 5 UTP cable.
The AR8228/AR8229 have up to three GMII/RGMII/TMII/MII interfaces to allow connection to host CPU in xDSL/Cable/Wi-Fi routers.
AR8228/AR8229 supports up to 9K Jumbo Frames which are typically used for high-performance connections to servers because they offer a smaller percentage of overhead on the link for more efficiency.
SPI or EEPROM interfaces provide easy programming on-chip functions even in unmanaged environments.
QoS functionality allows switch traffic to be given different classes of priority, for example, voice traffic for IP phone applications, video traffic for multimedia applications, or data traffic.
Up to 4k Virtual LANs (VLANs) can be set up via the SPI port for separation of different users or groups on the network.
32 ACLs can reduce CPU effort for VLAN/QOS/DSCP/forward mapping and remapping based on Layer1 to Layer4 information. Support for 16 PPPoE header removal sessions can increase video quality and further offload the CPU.
Hardware IGMP V1/V2/V3 (lite) and MLD1/2 (lite) is an innovation for
IPTV service control without CPU effort.
Full QinQ support allows independent routing and QoS decisions based on destination and traffic types in triple play applications.
Qualcomm EDGE,™ ETHOS-Designed Green Ethernet, power-saving features increases energy efficiency in disconnect or idle states while optimizing power consumption in active links based on cable length.
