Channel bonding combines several DOCSIS channels together to significantly increase data rates when compared to the speed of today’s cable modems. Announced today is the new Broadcom ® BCM3255 set-top box chip that incorporates this channel bonding technique. This new chip can support up to 120 Megabits per second (Mbps) downstream data rates, enabling next generation media centers to support an all-IP network platform, such as Comcast’s RNG family of devices. Moving to an all IP-based platform for voice, video, and data content helps to decrease MSOs network operating costs while enabling the network to support fast high-definition video downloads, high bit rate services and other IP voice and video services.

“Increasing the speed and performance capabilities of the cable network is a key element for MSOs as more and more telecommunications operators install fast, fiber-to-the-curb networks,” said Daniel Marotta, Senior Vice President and General Manager of Broadcom’s Broadband Communications Group. “Our new cable TV set-top box chip sets a benchmark for the industry enabling MSOs to deploy new set-top boxes and media centers today that can support the transition to an all-IP network.”
