Zarlink Semiconductor has responded to market demand by integrating its key DVB-T compliant COFDM demodulation technology with Set Top Box functionality (MPEG-2 A/V decoder and system interfaces) together with a high performance CPU to offer a "DVB-T On-a-Chip" solution.

The ZL10311 DVB-T On-a-Chip, can address a wide range of DVB-T consumer electronic products. At the entry level it can be used to build ultra-compact Free-To-View Digital TV adaptors (such as for FreeView in the UK), yet consumes less than 4W of power in full operational mode.

This level of compactness also considerably eases the integration of DVB-T receiver technology inside integrated Digital TV sets (iDTV's) where space considerations and thermal management are key design issues.

The ZL10311 is based upon an industry standard PowerPC 405TM RISC processor, which has Virtual and Memory Management sub-systems. This permits the ZL10311 to be effectively deployed in compelling applications such as interactive Digital TV which are able to exploit the superior processing performance offered by the PowerPC 
processor core.

The PowerPC provides an ideal platform for running robust open standard operating systems such as Linux which can benefit system developers in a number of key areas:

• Unified software development environment, from entry level basic channel zapper systems through to fully interactive high performance Digital Set Top Boxes.
• Re-use of software code from multiple projects
• Exploit software code developed in the Linux community.
• Low cost-per-seat software development environment.
• Familiar software development environment.
• Royalty free.

Also available is the ZL10311 DVB-T On-a-Chip, which additionally offers Dolby^® Digital¹ multi-channel audio decoding, and MacrovisionTM Copy Protection for applications requiring Dolby^® Audio and Pay TV services.
