Qualcomm Atheros Inc. has rolled out its AR7420 chipset that enables devices that provide fast, wired networking connectivity through existing household electrical wiring. The device targets consumers and service providers that offer connectivity solutions, stated the company.

The AR7420 is a powerline communications (PLC) transceiver IC that enables HomePlug AV-based and IEEE 1901-compliant products. The chipset is the latest in Qualcomm Atheros' AMP Powerline technology portfolio and is optimized for embedded solutions and small form-factor standalone adapters. The AR7420 is designed for multimedia applications and delivers up to 500Mbit/s of powerline performance. The company added that the chipset does this in a cost-effective approach to support high throughput connectivity in high volume applications.

Ideal either in standalone powerline equipment or in HyFi hybrid networking designs using Qualcomm Atheros' WiFi technology, the AR7420 chipset operates over a wider spectrum (2-68MHz), said the company. It also delivers more than twice the PHY rate speed of HomePlug AV solutions. The fifth-generation HomePlug AV-based IC also delivers carrier-grade performance with support for multicast IPTV, noted Qualcomm Atheros. Additionally, it touts reliable quality of service and whole home coverage. Combined with the wireless and Ethernet portfolio of products, the AR7420 enables hybrid networking routers, extenders and embedded products.

The AR7420 chip includes an MII/RMII host interface, integrated memory and 10/100 low power Ethernet PHY. The AR1540 line driver IC is a companion chip that provides signal optimization and multiple country support.

Samples of the AR7420 chip will be available by 4Q11.
