BCM3216

Description

The BCM3216 is a highly integrated DOCSIS 3.0 CMTS MAC IC for use in DOCSIS 3.0 CMTS products. Based on cost-effective hardware-processing engines, the BCM3216 provides a powerful yet cost-effective solution for a variety of CMTS architectures. With hardware support for bonding traffic reassembly, concatenation parsing, fragment reassembly, payload header suppression, and advanced physical-layer data rates, the BCM3216 serves as the heart of a next-generation CMTS.

The BCM3216 performs packet reassembly for bonded traffic, DES and AES decryption, fragment reassembly, deconcatenation, payload header expansion, Propane® packet acceleration, upstream MIB statistic gathering, and priority queuing for the resultant packets. DOCSIS MAC management messages can be forwarded to different destinations than data packets for a flexible interface to both a Network Processing Engine and System Controller using standard protocols.
