CSR's tuneX® product line expertly combines hardware and software to provide automotive OEMs with a highly cost-effective software-defined radio (SDR) solution.The pin-compatible front-end tuner chip offers leading RF performance across all radio standards including AM/FM, DAB, T-DMB, DRM and HD Radio™, eliminating the need for OEMs to implement dedicated hardware for each region.
This ‘regionalization’ and differentiation is performed in the software element of tuneX. Demodulation is also migrated from the hardware element to software, eliminating the need for a dedicated car radio processor. Processing is carried out on the SoC’s RAM and Flash memory systems simplifying for the OEM all of the effort required in development, qualification and purchasing. This allows OEMs to differentiate their radio products and fine-tune performance parameters at the front end and the demodulator while realizing lower BOM costs. It also offers the flexibility to tweak performance, enable field upgrades for new services or patches and add additional features in the future. tuneX is perfectly suited for car radio, display audio, infotainment, receiver box and smart antenna applications.
CSR offers tuneX front-ends or tuneX software demodulators as standalone products or as part of a fully integrated radio package on the newly released CSRatlas7™. CSR can also offer tuneX as a solution working on a third-party platform.
