Powerline Networking Chipset

The Piranha? Piranha chipset consists of the CS1100 and the AD9875. The CS1100 is a single-chip HomePlug? 1.0 compliant MAC/PHY for use in home powerline networking products. The CS1100 enables Ethernetclass networking over existing electrical wiring with full quality-of-service support and privacy ensured through encryption. The AD9875 HomePlug MixedSignal Front End is a low-power, low-cost converter for powerline communications. Target applications for the Piranha chipset include PC network adapters, residential gateways including set-top boxes, and a wide range of entertainment and communication devices.
