DOCSIS/EuroDOCSIS-1.0
•
The BCM93212 is a termination system (CMTS)and 1.1
based cable modem
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
•
Provides complimentary system to the BCM93345,
•
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.
BCM93350 and BCM93360 subscriber cable modem
and residential gateway reference design for product
development and testing.
•
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
•
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
