DOCSIS®/EuroDOCSIS™ 3.0 Cable Gateway SoC

Broadcom's BCM33843 provides a simple migration path to 16x4 and is pin compatible and leverages the same software and system design as Broadcom's widely deployed BCM3383 DOCSIS 3.0 cable gateway SoC. This enables operators to leverage existing designs to quickly deploy additional channels and more bandwidth.

The BCM33843 supports DOCSIS and digital video on any frequency eliminating limitations of "block" tuners. When combined with Broadcom's set-top box SoC with fast acquisition technology, video channels can be pre-tuned and users can enjoy the experience of Broadcom's FastRTV™ fast channel change technology.
