Broadcom Corporation recently revealed a new reference platform for operators in emerging markets to more cost-effectively deploy two-way set-top box (STB) solutions with high definition (HD) and Data Over Cable Service Interface Specification (DOCSIS) 2.0.

Broadcom's BCM97584SFF reference design combines the BCM3308 with the BCM7584. The BCM3308 is a single-chip DOCSIS 2.0 cable modem device that is based on the company's series of DOCSIS 2.0 devices. The BCM7584 is the first low-cost HD digital cable STB SoC to integrate Full-Band Capture technology and IP video server technology.

The company's Full Band Capture technology enables the BCM7584's four demodulators to simultaneously access broadcast video and tune DOCSIS, with complete channel flexibility up to 1GHz. Full Band Capture technology also enables advanced remote cable diagnostics, which can mitigate physical customer service calls and save operator substantial service call expenses.

In addition to Full Band Capture, the set-top box offering features a 3D graphics processing unit to support advanced user interfaces using HTML5; advanced diagnostics with spectrum analyser, and FastRTV, Broadcom's innovative solution that improves channel change times to nearly instant speeds. Performing at more than 2000 DMIPS, the new HD DOCSIS 2.0 STB solution provides twice the performance of Broadcom's previous generation single-chip, and offers the latest advanced security with support for state-of-the-art of conditional access security (CAS) and digital rights management (DRM) technologies.

To further enable the rapid development and deployment of the new HD DOCSIS 2.0 STB solution, Broadcom offers a complete single-board reference design with certified DOCSIS 2.0 software and Nexus-Trellis STB software. Broadcom's Nexus-Trellis STB software supports many popular middleware solutions, including the new Open Source-based Reference Development Kit (RDK), to enable rapid porting and software development from BCM7019-based designs. Nexus-Trellis is complemented by a large set of open application libraries supporting popular extensions like DLNA, Miracast, OpenGL, DirectFB, and Gstreamer.

Both the BCM7584 and the BCM3308 are shipping. The low-cost BCM97584SFF reference design is currently available.
