Broadcom Releases New Low Power Low Cost Cable Modem SoC

By Nathesh, TMCnet Contributor

Broadcom (News - Alert), a provider of semiconductors for wired and wireless communications, has released a new DOCSIS/Euro-DOCSIS 3.0 cable modem system-on-a-chip, or “SoC,” solution – the BCM3382 for enhanced RF performance at low power and cost.
DOCSIS defines the communications and operation support interface requirements for a data over cable system. It permits the addition of high-speed data transfer to an existing Cable TV, or “CATV,” system and is employed by many cable television operators to provide Internet access over their existing hybrid fiber coaxial, or “HFC,” infrastructure.
Broadcom’s BCM3382 comes packed with second generation integrated tuners that enables enhanced RF performance while at the same time implementing advanced power management functionality. These new improvements are supposed to help manufacturers develop high performance DOCSIS 3.0 products for voice and data applications in a cost effective design.
The BCM3382 as a DOCSIS 3.0 based solution will support increased bandwidth so that cable operators can satisfy the increasing customer demand for advanced services in the home and offer new services including IPTV (News - Alert), secure virtual private networks, or “VPNs,” for telecommuters, full-featured IP telephony, video conferencing, local web hosting, and peer-to-peer networking applications such as music downloading and file sharing.
One of the key features of BCM3382 is that it has a powerful processing architecture that enables line speed data rates and the ability to maximize the total system performance of a DOCSIS or EuroDOCSIS 3.0 system. The integrated dynamic power management controllers in it offer efficient power management system capable of managing and shutting down unused system components in real-time.
The new SoC is fully compliant with the DOCSIS 3.0/2.0/1.x specification and adds support for Broadcom's BroadVoice family of voice codec, the existing CablexChange voice software suite and CableMedea gateway software.
Jay Kirchoff, Senior Director of Product Marketing at Cable Broadband line of business has commented that by making use of their high performance and cost-optimized DOCSIS/EuroDOCSIS 3.0 product family, the Broadcom BCM3382 reduces power requirements and overall costs further enabling mass deployments of DOCSIS 3.0 data modems and embedded multimedia terminal adapter.
In related news, Broadcom enabled affordable IP digital services with new STB and their BCM4325 combo chip provided wireless connectivity.
