Broadcom Announces Cable TV STB Chip with Integrated Channel Bonding Technology
February 1, 2006
Wireless Design & Development Magazine News Release
Broadcom has announced the front-end cable TV set-top box (STB) chip with integrated channel bonding technology. Channel bonding is a DOCSIS 3.0 feature that increases the transmission speed of a cable TV network, enabling multi service operators (MSOs) to migrate to an all- Internet Protocol (IP) network platform. Addressing voice, video and data, the all-IP network enables MSOs to provide significant benefits such as additional cable and local broadcast channels, content flexibility and improved network efficiency.
The BCM3255 is an integrated front-end chip for HD DVR cable TV set-top boxes and media centers. The chip integrates three 1024/256 QAM in-band demodulators, an out-of-band demodulator, DOCSIS 2.0+/3.0 cable modem technology, USB 2.0 MAC and PHY, and a 10/100 Fast Ethernet MAC (media access controller) and PHY (physical layer device). An integrated 800 DMIPS processor provides support for these next generation features including DOCSIS 2.0+/3.0 and channel bonding resequencing, DOCSIS set-top gateway (DSG) protocols, as well as networking protocol support for TCIP, IPnP and IPv6. The BCM3255 is available in sample quantities. The chip is packaged in a 416-pin PBGA and is priced at $32 each in 10,000 piece quantities.
