DOCSIS/EuroDOCSIS 1.1 ADVANCED CABLE MODEM TERMINATION SYSTEM
BCM93212 FEATURES
• The BCM93212 is a DOCSIS/EuroDOCSIS-1.0 and 1.1
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
SUMMARY OF BENEFITS
• 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}
