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. 

HomePlug 1.0 MAC/PHY
• rate adaptive to 14 Mbps
• 0.18 micron CMOS process
• small footprint 100 pin LQFP
• integrated PLL
• low power 1.8V core 

Easy Product Integration
• emulates Ethernet PHY
• flexible host interface: MII or 8-bit Peripheral
• 3.3 V I/Os (5V tolerant host I/F)
• glueless interface to highly integrated mixed-signal front end
• direct support for link status LEDs

Flexible Processor-Based MAC
• supports multiple outstanding packets during segmentation and reassembly
• firmware is field-upgradeable and fully configurable from host (serial EEPROM not required) 

Design for Manufacture
• testability support – loopback at host interface, local and remote powerline nodes
• optional serial EEPROM - programmable in system
• JTAG Boundary scan 

Mixed-Signal Front End
• TX Path
   - 10 bit D/A, 100 MSPS
   - 2x oversampling digital low-pass filter simplifies reconstruction filter
• RX path
