BCM93212

Description

The Broadcom BCM93212 QAMLink® DOCSIS/EuroDOCSIS Cable Modem Termination System (CMTS) Reference Design represents the industry's first complete DOCSIS/EuroDOCSIS based silicon solution with TDMA upstream and advanced PHY downstream functions for the headend cable plant. The BCM93212 CMTS supports the DOCSIS/EuroDOCSIS 1.0 and 1.1 specification enabling QoS for the simultaneous processing of voice, video and data on a prioritized basis. The BCM93212 CMTS includes the BCM3034 Universal Advanced PHY QAMLink® Modulator, the BCM3212 DOCSIS/EuroDOCSIS 1.1 CMTS MAC and the BCM3138 Universal TDMA Burst Demodulator and provides all the necessary functionality required to receive and transmit high rate digital data to and from a cable plant.

Functions of BCM93212 include:

Hardware-supported messaging (ranging, registration, channel configuration)

Physical layer configurations (upstream baud rates, upstream channel descriptor and MAP variations, and FEC code-word size)

Baseline privacy support

Flexible PHY and MAC parameter settings and performance monitoring
