[Cogency Semiconductor Inc.] 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 - 10 bit A/D, 50 MSPS - -6 dB to 30 dB programmable gain amplifier Product Applications • powerline USB adapters • powerline to Ethernet bridges • powerline PCI NICs • DSL/cable modems • Residential Gateways • set-top boxes • multi-room audio and MP3 jukeboxes • VoIP telephones • game consoles • home security
