BCM3252 - Dual-Channel Front-End DOCSIS® 2.0+ STB IC with Channel Bonding

Dual-Channel Front-End DOCSIS® 2.0+ STB IC with Channel Bonding

Broadcom's ICs provide the solution for the next-generation interactive DOCSIS 2.0+, DSG HD AVC set-top box. The main sections include a front end (tuners, QAM, and DOCSIS), addressed by the BCM3420 and BCM3252, and a back end (HD AVC/VC-1/MPEG2 decoding, audio decode, HDMI, and peripherals, etc.), addressed by the BCM7402.

The BCM3252 IP Video Pipeline IC provides the integrated front-end solution for high-end set-top boxes. It has a high-performance processor that can address the tasks of DOCSIS 2.0+, channel-bonding resequencing, and network protocols such as TCPIP, UPnP, and IPv6. The BCM3252 is both DOCSIS- and EuroDOCSIS™-certified.

  • Dual QAM in-band demodulators
  • Out-of-band (OOB) demodulator for support of DVS-178 and DVS-167
  • The BCM3252 provides a complete front-end solution for next-generation set-top box products. North America and international markets enable a single design to be deployed on a worldwide basis
  • Able to support IP video data rates at up to 80 Mbps, allowing for future transition to an all IP network
