NXP Semiconductors NV debuts a flexible digital radio co-processor for car entertainment systems. The SAF356x series supports DAB, DAB+, and T-DMB reception, as well as HD Radio for both single- and dual-tuner applications. The co-processor is a multi-standard baseband processor for digital terrestrial radio systems, with software that can be modified to support additional features in the future, including standards such as DRM or DRM+.

Because the NXP SAF356x is a multi-standard processor, it can replace multiple ICs used in car entertainment systems. Thus, it enables car OEMs and tier one suppliers to cut total cost of ownership for digital reception systems. It also eases future-proof design and provides software upgrade flexibility.

According to Michael G�rtler, development manager, Fujitsu-Ten Europe GmbH, " we only have to invest in one hardware platform and still have the flexibility we need to fulfill the different demands of our many customers. What NXP offers as a package is also unique in the market, as the company is able to support not only the chip, but the complete application including its own DAB software."

The SAF356x is a digital radio processor that demodulates and processes digital terrestrial radio signals and outputs the decoded audio and data. For HD Radio, it uses the AM/FM signals from NXP's radio/audio DSPs such as SAF7741 or its newest RFCMOS-based digital one-chip TEF663x. The SAF356x series makes it easy for customers to build DAB systems based on the same hardware, with the addition of a DAB tuner module and application of new automotive-grade NXP software for DAB, DAB+ and T-DMB for single- and dual-tuner applications with one baseband processor.

Other benefits of terrestrial radio processor systems using the SAF356x include facilitated system design featuring a modular approach with easy to use co-processor to AM/FM radio/audio DSPs, high-level API and automotive-grade software reducing development effort; full feature set including audio source decoding to reduce load on the application and host processor; differentiating features of NXP's DAB software enabled by scaling external SDRAM including DAB-FM blending, timeshift for pausing radio playback and resuming listening later and reception improvement algorithms.

Compared to analog AM/FM, digital terrestrial radio improves the radio listening experience and increases the choice of programs, leading to increasing adoption around the globe. In the United States, HD Radio is now a core element of the in-car entertainment package offered by leading vehicle manufacturers, and NXP is the leading supplier of ICs for automotive HD Radio systems. In Europe, led by Britain, governments have chosen the DAB/DAB+/T-DMB family of standards, and many other European countries such as Germany, France and Italy have shown renewed enthusiasm for DAB, DAB+ and T-DMB respectively.

The NXP SAF356x is available for mass production.
