BCM3381

Description

The BCM3381 is the industry's first integrated, single-chip channel bonded cable modem solution, delivering over 100 Mbps data rates. When used with Broadcom's silicon tuner solutions, the resulting channel bonded modem does not have additional limitations on channel location, modulation parameters, or power levels, enabling maximum flexibility for channel bonding. Additionally, with advanced integration, the BCM3381 requires no costly FPGA or external logic to implement DOCSIS channel bonding. DOCSIS 2.0 compliant, the BCM3381 is interoperable on todays networks, and supports channel bonding with existing CMTS hardware enabling immediate deployment.

The BCM3381 combines RF receivers with advanced QAM and S-CDMA demodulators, an advanced QAM transmitter, a complete DOCSIS 2.0+ Media Access Controller (MAC) with channel-bonding capability, a 800-DMIPS communication processor, a 16-bit, 133-MHz DDR266 DRAM interface, and integrated USB 2.0 and Ethernet and ports.
