Atheros Communications Inc. expands its networking portfolio with the launch of AR8021, claimed to be the smallest, most cost competitive, single-port GbE PHY.

Atheros said that its solution offers a reduction of more than 60 percent in package size compared to the nearest competitive solution in the market. AR8021 is available in a 6-by-6mm, 48-pin, QFN package. This GbE PHY footprint results in the lowest BOM cost in the market, reducing price barriers to widespread adoption of GbE PHY technology in various computing and networking applications.

AR8021 serves a growing number of devices that benefit from Gbit throughput including notebook and desktop PCs, wired and wireless routers, gateways, STBs, printers, gaming platforms and network storage devices.

According to Atheros, the GbE performance effectively breaks the networking bottleneck caused by the increasing bandwidth requirements associated with converged triple-play applicationsdata, voice, and videothroughout home and business environments.

The benefits of GbE networking are so evident that the number of PC platforms using GbE technology outnumbers now those based on Fast Ethernet. The SMB networking market is also dominated by GbE technology, with various GbE-enabled solutions.

Low cost, multifeature solution
AR8021's footprint is claimed to provide a low cost, low power design, while delivering a rich feature set.

The GbE PHY is optimized for low power operation and consumes less than 650mW. The design also features low power modes that leverage internal DSP power-saving schemes.

AR8021 is compliant with IEEE 802.3 specifications. The device features a 10/100/1000Mbps triple-speed transceiver with an RGMII interface. AR8021's DSP architecture delivers robust performance with excellent tolerance to NEXT, FEXT, echo and other environmental and electronic noise.

In terms of value-added features, Atheros' easy-to-use Cable Diagnostic Test allows IT staff and service providers to easily check the health of the network cable connections for any open or short fault locations.

AR8021, which was developed by Atheros' design center in Shanghai, China, will begin sampling in late May to key customers.
