Broadcom Chips Power Downstream Channel Bonding Modems

Broadcom Corporation (Nasdaq: BRCM), a global leader in semiconductors for wired and wireless communications, announced that it has shipped more than one million units of its advanced channel bonding cable modem silicon for downstream channel bonding cable modems. Compatible with existing DOCSIS® 2.0 and next generation cable modem termination system (CMTS) equipment, Broadcom® cable modem silicon delivers downstream data rates of up to 150 Megabits per second (Mbps) and enables multiple service operators (MSOs) to deploy downstream channel bonding functionality immediately, without delays or costly upgrades to their CMTS infrastructures.

Channel bonding is often cited as the most significant feature of next generation DOCSIS 3.0 products. Whereas DOCSIS2.0 products are limited to single downstream and upstream channels, next generation products will use channel bonding to combine the bandwidth of several DOCSIS channels to significantly increase data rates. Downstream channel bonding is the first of the next generation features to be deployed on a large scale. With Broadcom supporting downstream channel bonding since 2006, it continues to be the leading supplier of channel bonded cable modem silicon.

As part of the previously announced Broadcom BCM3255 family of channel bonding cable modem silicon, Broadcom’s latest BCM3381 solution enables MSO customers to provide services using downstream channel bonding, well ahead of competing products. With integrated channel bonding and downstream data rates fast approaching 150 Mbps, Broadcom’s single-chip BCM3381 cable modem solution supports ultra high speed data services, reduces the time required for video downloads for video-on-demand (VoD) services, and also enables the delivery of IP video content.

The success of Broadcom’s single-chip BCM3381 channel bonded cable modem solution is due in large part to its compatibility with existing DOCSIS 2.0 and next generation CMTS equipment, enabling MSOs to deploy channel bonding functionality immediately. Given the growing demand by MSOs for advanced capabilities today, Broadcom has already shipped over one million units of its channel bonding cable modem silicon.

“Worldwide demand for cost effective, high speed cable services has risen dramatically as MSOs extend their product offerings with advanced capabilities such as IPTV,” said Jay Kirchoff, Senior Director of Product Marketing for Broadcom’s Cable TV line of business. “We’re seeing strong and growing demand from customers in all regions of the world as virtually no additional investments in the CMTS infrastructure will be required for operators to enable 100+Mbps downstream data rates provided by our BCM3381 solution.”

“Being a market leading service provider, Hanaro Telecom has already successfully deployed world class 100Mbps IPTV-capable cable modems built on Broadcom’s BCM3381 solution,” said Peter Park, Vice President of Hanaro Telecom, Inc. “Since the market in South Korea is very competitive and based on immediate delivery of information, our family of BCM3381-based data modems has allowed us to deploy high speed data and IPTV services today, while offering forward compatibility with the next generation standard.”

Since Hanaro’s successful introduction of IPTV via DOCSIS downstream channel bonding technology, several other MSOs have announced downstream channel bonding plans supporting IPTV or high speed video downloads. The first of these BCM3381 applications included a gateway that supported ultra high speed data traffic, and IP video traffic, delivered to an IPTV set top box. For this application, the downstream channel bonding allowed IPTV content to be sent to multiple TVs in a single home and to multiple IPTV subscribers in a neighborhood.

Technical Information
The BCM3381 is the industry’s leading single-chip DOCSIS/EuroDOCSIS channel bonding cable modem solution that combines radio frequency (RF) receivers in support of both advanced QAM and S-CDMA, an advanced QAM transmitter, a complete DOCSIS 2.0+ media access controller (MAC) with channel bonding capabilities, an 800-DMIPS communications processor, a DDR266 DRAM interface, Ethernet and USB interfaces, and expansion capabilities to support VoIP and wireless connectivity. With support for IPv6, the BCM3381 is ready for networks supporting this next generation Internet standard.
