Brief

QAMLINK HIGH-PERFORMANCE, SINGLE-CHIP CABLE MODEM

B C M 3 3 4 5 F E A T U R E S

S U M M A R Y O F B E N E F I T S

State-of-the-art, single-chip DOCSIS/EuroDOCSIS

1.0/1.1 cable modem providing unprecedented levels of

integration and performance

Results in simplified BOM—reduces component count,

improves assembly process and results in lowest

overall system cost for DOCSIS/ EuroDOCSIS 1.0/1.1

cable modem.

DOCSIS/EuroDOCSIS 1.0/1.1 MAC is compatible

with existing Cable Modem application code, resulting

in minimum time to market.

•

The BCM3345 integrates:

• Advanced QAMLink transceiver supporting Annex A/B/C

operation

• DOCSIS/EuroDOCSIS 1.0/1.1 MAC

• High-performance, 140-MHz MIPS-32 CPU

• Advanced QAMLink‚ downstream demodulator, supporting

4/16/32/64/128/256 QAM

140-MHz MIPS-32 CPU provides 66% improvement

•

in packet throughput over prior generations.

Advanced QAMLink modulator/demodulator

• Advanced QAMLink upstream modulator, supporting

2/4/8/16 QAM

provides superior performance in noisy plant

environments.

• Upstream power amplifier

• 10/100 Ethernet MAC/PHY with MII interface

• Single 28MHz reference crystal

On-chip Propane supports DOCSIS/EuroDOCSIS

•

based packet acceleration.

• USB 1.1 slave port with integrated transceiver

• 100-MHz SDRAM interface

Integrated 10/100 Ethernet MAC/PHY with MII

eliminates the need for external Ethernet support.

Advanced RF and control interface to silicon tuner for

•

Fully USB 1.1 compliant interface enables simple Plug

DOCSIS/EuroDOCSIS solutions

and Play installations.

EJTAG embedded ICE support

•

EJTAG embedded ICE support is compatible with

existing MIPS32 development tools, improving

software development and testing.
