BCM93212 is a DOCSIS/EuroDOCSIS-1.0 and 1.1
• The
based cable modem termination system (CMTS)
reference design which incorporates:
• 64/256/512/1024 QAM downstream modulation with FEC
• QPSK, 16, 32 and 64 QAM burst TDMA demodulation
• Digitally generated IF carrier that meets
DOCSIS/EuroDOCSIS-1.1 and 1.1 spectral purity requirements
without a SAW filter
• DOCSIS/EuroDOCSIS programmable downstream transmit IF
carrier center frequency and channel bandwidth
• Master/Slave MAP, reference clock, timestamp synchronization,
and 10/100/1000BASE-T front panel connectors
• BCM3212 MAC hardware that simplifies registration, ranging,
fragmentation, concatenation, encryption, and payload header
suppression
• Scheduler support for DOCSIS 1.1 best effort, polled, and
unsolicited grant service flows
•
The BCM93212 basic system parameters include:
• A BCM3212 Compact PCI V2.1 compliant base board with
plug in connectors for 64/256/512/1024 QAM modulator and
TDMA demodulator daughter cards
Support
for one QAM downstream channel
•
• Support for six programmable upstream channels that support
all DOCSIS 1.0 / 1.1 and TDMA symbol rates and
demodulation types.
• 10/100/1000BASE-T network side interface
• Seamless upgrade for legacy BCM93210 CMTS platforms
using QNX RTOS

• Provides complimentary system to the BCM93345,
BCM93350 and BCM93360 subscriber cable modem
and residential gateway reference design for product
development and testing.
• Supports DOCSIS/EuroDOCSIS 1.1 fragmentation
and concatenation for Quality of Service (QoS).
• Provides a highly integrated 6 x 1 CMTS reference
design in a compact PCI form factor.
Accelerates
software development by providing source
•
code for core software functionality and low level
diagnostics.
• Reduces customers’ internal development expenses.
• Leverages years of development work embodied in the
Broadcom BCM93210 reference design.
• Based on Broadcom’s field-proven QAMLink
technology.
• Reference design comes complete with:
• Schematics and Gerber files
• Bill of Materials (BOM)
• Data sheets
• Software source code and API

The Broadcom BCM93212 QAMLink® DOCSIS/EuroDOCSIS
Cable Modem Termination System (CMTS) Reference Design
represents the industry’s first complete DOCSIS/EuroDOCSISbased 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)
Downstream
SDRAM
(PHS,
output
queues)
Memory
The BCM93212 is complemented at the subscriber end by the
BCM93345,
BCM93350
and
the
BCM93360,
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.
