NXP Semiconductors announced the availability of the SAF356x series, a flexible digital radio co-processor for car entertainment systems supporting DAB, DAB+ and T-DMB reception, as well as HD Radio. All standards are supported for both single- and dual-tuner applications. The SAF356x is the market’s first 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+.

As a multi-standard processor which can replace multiple ICs used in car entertainment systems today allowing future-proof design and software upgrade flexibility, the NXP SAF356x enables car OEMs and Tier One suppliers to reduce their total cost of ownership for digital reception systems.

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 leading radio/audio DSPs such as SAF7741 or its newest RFCMOS-based digital one-chip TEF663x. As the leading baseband processor for HD radio in cars, the SAF356x series makes it easy for customers to also 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.

Major benefits of terrestrial radio processor systems using the SAF356x:

  • Lower cost of ownership for digital terrestrial radio by supporting multiple standards and tuner configurations with one IC
    • HD Radio (SAF3560)
    • DAB, DAB+, T-DMB (SAF3561)
    • Single- as well as dual-tuner applications with audio plus data
  • Facilitated system design
    • 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
    • DAB-FM blending
    • Timeshift for pausing radio playback and resuming listening later
    • Reception improvement algorithms
