HPNA 2.0

The Broadcom BCM3352 represents a new and unprecedented

level of integration for PacketCable Multimedia Terminal

Adapters (MTA.) The BCM3352 provides a unique solution for

low power and cost effective MTAs that can deliver primary line

VoIP cable telephony and broadband data services over phone

lines worldwide.

Key modules integrated in the BCM3352 include:

• Enhanced VoIP DOCSIS/EuroDOCSIS 1.0/1.1 based MAC

integrating a wirespeed DES encryption/decryption engine,

full DOCSIS/EuroDOCSIS 1.1 QoS, support for 16 SIDS in

the downstream, 256 multicast/and Unicast DA CAM,

16 independent DMA controlled upstream queues, as well as

extended network management MIB and diagnostic features.

• 200+ MIPS VoIP/FoIP DSP with patented PacketSync™

delivering four channels of compressed voice packets,

including G.711, G.726, G.729a/b/e, and G.728 Vocoders,

plus T.38 Fax Relay.

• Integrated iLine32™ HPNA 2.0 home phone line interface

that eliminates hundreds of dollars worth of additional

telephone and Ethernet wiring.

• High-performance 120 MIPS, 100-MHz MIPS32 processor

with a 4K two-way set associative I-cache and a 4K two-way

associative D-cache.

• Broadcom Propane™ software support for enhanced

bandwidth efficiency and turbo modem performance.

• Integrated 10/100 Ethernet MAC for support of small

business integrated access device applications.

• IPSec module with single-DES (CBC & ECB modes), triple-

DES (CBC & ECB modes), MD-5 and SHA authentication

in hardware, providing support for Virtual Private Networks

(VPNs).

• Integrated four-channel FlexiVoice™ Voice Codec with

individual line programmable filter coefficients, providing

optimum performance for both V.90 modem and voice

applications.
