ETC CS1100

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.
