BCM93212

DOCSIS®/EuroDOCSIS™ 1.1 Advanced Cable Modem Terminal

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 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

    • The BCM93212 is a DOCSIS/EuroDOCSIS-1.0 and 1.1 based cable modem termination system (CMTS) reference design
    • 64/256/512/1024 QAM downstream modulation with FEC
    • Provides complimentary system to the BCM93350 and BCM93360 subscriber cable modem and residential gateway reference designs for product development and testing
