• Manufacturer Part Number: BCM93212-E
• Description: DOCSIS/EuroDOCSIS 1.1 ADVANCED CABLE MODEM TERMINATION SYSTEM
• Manufacturer: BOARDCOM [Broadcom Corporation.]

The Broadcom BCM93212 QAMLink
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
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
• Physical layer configurations (upstream baud rates, upstream
• Baseline privacy support
• Flexible PHY and MAC parameter settings and performance

The BCM93212 is complemented at the subscriber end by the
BCM93345,
DOCSIS/EuroDOCSIS-based cable modem and residential
gateway silicon solutions. The BCM93360 is based on the
BCM3360 single-chip residential gateway, which integrates all
the major functions of a cable modem into a single device.
Together, the BCM93212 and the BCM93360 provide vendors
with a seamless end-to-end silicon solution for development and
testing of an DOCSIS/EuroDOCSIS-based cable modem and
cable modem termination system with TDMA upstream and
advanced PHY downstream functions.
