New CSRatlas7™ SoC and tuneX® Products Bring Exciting Platform Advantages for Display Audio Infotainment and SDR Tuners

Another advantage is support for concurrent reception and scalability benefits when moving from single tuner to multi-tuner concepts. tuneX leverages system memory when a user changes to an alternative radio channel. As soon as two or more standards are received concurrently in a dual or multi tuner design, the signals are available in the software audio buffers and users can blend between channels immediately with no noticeable audio delay.

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™ platform. CSR can also offer tuneX as a solution working on a third-party platform.
