BCM3255

Single-Chip Front-End DOCSIS® 2.0+ IC High-Definition Set-top Box (STB) IC

Currently Viewing:

The Broadcom BCM3255 Set-top Box (STB) chip with integrated channel bonding combines several DOCSIS® channels together to significantly increase data rates.
 
Broadcom's BCM3255 chip supports up to 120 megabits-per-second (Mb/s) downstream data rates, enabling next-generation media centers to support an all-IP network platform. Moving to an all IP-based platform for voice, video and data content helps to decrease 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.
