Brief
DUAL-CHANNEL FRONT-END DOCSIS^® 2.0+ STB IC WITH
CHANNEL BONDING
FEATURES
SUMMARY OF BENEFITS
• Dual QAM in-band demodulators
• Out-of-band (OOB) demodulator for support of DVS-178 and
DVS-167
• 800DMIPS dual-threaded R4K MIPS processor
• DOCSIS^®/EuroDOCSIS™ 2.0+ including DSG and channel
bonding
• DOCSIS and channel bonding code supplied by Broadcom^®
• DAVIC MAC
• USB 2.0 MAC and PHY (full data rate USB supported)
• PCI
• Boot from unified back-end Flash (i.e., Flash connected to
BCM7038, BCM7400, BCM7401, or BCM7402)
• Ethernet MAC and PHY
• BOM savings include integrated regulators, VCX0, and
upstream amplifier
• IPv6 supported
• 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.
• Software 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.
