• The BCM3350 integrates all the silicon components of
a cable modem, resulting in dramatic overall system
cost reduction.
• Includes a 100 MIPS CPU with EJTAG embedded
ICE support for ease of software development and
debug.
• QAMLink transceiver supporting Annex A/B/C operation
• DOCSIS/EuroDOCSIS 1.0/1.1 based MAC
• Displays superior performance in noisy plant
environments as a result of Broadcom’s newest
generation of Broadcom QAMLink technology.
• High performance 100 MIPS CPU
