Broadcom Corp. has announced a 65nm 5-port GbE switch in a single-chip design. Claimed to be an industry-first, the new device promises to drive the deployment of GbE connectivity to consumer electronic devices and home networking equipment.

The 65nm process technology enabled an intelligent switching solution with the industry's smallest footprint, the company said, achieving performance enhancements and a 30-percent reduction in power versus previous generations of Broadcom silicon. For the first time, a GbE switch is now available with a power level and price point that can drive the transition from Fast Ethernet (FE) to GbE in home routers, residential gateways, STBs and other CE devices.

Broadband connectivity is now ubiquitous and the demand to share a high-speed connection and multimedia content throughout the home is growing by leaps and bounds. The digital home is quickly becoming a reality, and whether users download movies, share music and photos, or telecommute using a VPN router, they want to share all of their content across one home network.

The desire to share bandwidth-intensive content across a large number of computers and CE devices puts a strain on home networks. This is particularly true in the WLAN market where the migration from 802.11g to 802.11n Wi-Fi technology will boost network speeds in excess of 100Mbits/s. As a result, home networks will need to transition from FE to GbE connectivity to create the wired infrastructure necessary to support these increased network speeds.

The new BCM53115 GbE switch promises better network performance in a smaller, cooler device. It offers a comprehensive L2 feature set, support for DSL/cable modem and WLAN connectivity, and features 5Gbits of switching capacity on a single chip.

The new GbE switch is also unique in its ability to provide intelligent traffic management through Broadcom's compact field processor (CFP), which provides QoS for better user experience. The CFP makes it possible for consumers to share HD video, download music to a handheld multimedia player, transfer photo libraries and make VoIP calls simultaneously across the same network.

Pricing for the BCM53115 is available upon request from the company.
