SUMMARY OF BENEFITS
• Results in simplified BOM—reduces component count,
improves assembly process and results in lowest
overall system cost for DOCSIS/ EuroDOCSIS 2.0
cable modem
• DOCSIS 1.1 Mac provides compatibility with existing
CM applications code resulting in minimum
time-to-market
• 200-MHz MIPS32™ CPU provides 40% improvement
in packet throughput over previous generations
• Advanced QAMLink® modulator/demodulator
provides superior performance in noisy plant
environment
• On-chip PROPANE supports DOCSIS/EuroDOCSIS
compatible 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
• Sixth-generation technology results in a highly-stable,
reliable product
