Broadcom Corp. has announced a new digital-to-analogue (DTA) system-on-a-chip (SoC) solution that enables cable set-top box (STB) OEMs to provide cable operators with a cost effective device that transitions analogue cable customers to digital broadcasting. The new Broadcom DTA chip paves the way for the expanded network capacity needed to provide additional high-definition (HD) content and is currently used by manufacturers building DTA converter boxes for Comcast.

The BCM3545 DTA SoC enables cable operators to move quickly and cost efficiently to all-digital infrastructures by delivering digital-quality video and audio service to existing analogue cable customers. Designed in 65nm, the single-chip BCM3545 cable DTA SoC provides significant benefits over larger process geometries by enabling lower power consumption, higher CPU and memory performance for fast channel changes, and higher levels of integration that result in smaller form factors and lower cost adapters, claims Broadcom. The new DTA chip is based upon the earlier generation BCM3543 SoC that is used in many terrestrial broadcast designs and is ENERGY STAR-compliant.

The BCM3545 DTA SoC is now in production. Pricing is available upon request.
