The BCM3252 provides a complete front-end solution for next-

generation set-top box products. North America and

international markets enable a single design to be deployed on

a worldwide basis.

Able to support IP video data rates at up to 80 Mbps, allowing

for future transition to an all IP network.

S oftware switchable from broadcast (video channel

configuration) to channel bonding, enabling in field-network

configuration transitions.

High-performance processor capable of supporting DOCSIS/

EuroDOCSIS 2.0+, channel bonding, and other network-

centric applications.

OOB provides support for existing OOB channels that are

used today. Facilitates move to DSG and DOCSIS.

USB 2.0, PCI, and Ethernet make for flexibility in connection

to back-end devices, BCM7038, BCM7400, BCM7401, and

BCM7402.

BOM savings resulting from integration enable lower overall

set-top box cost.

Broadcom-supplied code for channel bonding and DOCSIS

enables quick time-to-market.
