| BCM3345 PRODUCT (R) Brief OF BENEFITS QAMLINK(R) HIGH-PERFORMANCE, SINGLE-CHIP CABLE MODEM BCM3345 FEATURES SUMMARY State-of-the-art, single-chip DOCSIS/EuroDOCSIS * 1.0/1.1 cable modem providing unprecedented levels of Results in simplified BOM--reduces component * improves assembly process and results in lowest count, * * Advanced QAMLink integration and performance The BCM3345 integrates: * Advanced RF and control interface to silicon tuner for DOCSIS/EuroDOCSIS solutions * EJTAG embedded ICE support * On-chip support for Propane packet acceleration * 1.8/3.3 volt operation * 312-pin PBGA package TM (R) transceiver supporting Annex A/B/C operation * DOCSIS/EuroDOCSIS 1.0/1.1 MAC * High-performance, 140-MHz MIPS-32 CPU * Advanced QAMLink downstream demodulator, supporting 4/16/32/64/128/256 QAM * Advanced QAMLink upstream modulator, supporting 2/4/8/16 QAM * Upstream power amplifier * 10/100 Ethernet MAC/PHY with MII interface * Single 28MHz reference crystal * USB 1.1 slave port with integrated transceiver * 100-MHz SDRAM interface * * * * * * * overall system cost for DOCSIS/ EuroDOCSIS 1.0/1.1 cable modem. DOCSIS/EuroDOCSIS 1.0/1.1 MAC is compatible with existing Cable Modem application code, resulting in minimum time to market. 140-MHz MIPS-32 CPU provides 66% improvement in packet throughput over prior generations. Advanced QAMLinkTM modulator/demodulator provides superior performance in noisy plant environments. On-chip Propane supports DOCSIS/EuroDOCSIS based packet acceleration. Integrated 10/100 Ethernet MAC/PHY with MII eliminates the need for external Ethernet support. Fully USB 1.1 compliant interface enables simple Plug and Play installations. EJTAG embedded ICE support is compatible with existing MIPS32 development tools, improving software development and testing. High-Performance, Single-Chip DOCSIS/EuroDOCSIS 1.1 Cable Modem SDRAM Diplexer Silicon Tuner SAW BCM3345 High Performance Single Chip DOCSIS/EuroDOCSIS 1.1 Cable Modem 10/100 Ethernet USB 1.1 FLASH |
