A digital radio chipset is offered as the first of its kind that enables simultaneous reception and processing of AM/FM and multiple digital-radio broadcasts (e.g. DAB+). This is a complete receiver solution based on one or more (up to 4) multi-standard RF ICs and a base-band processing IC running the full software stack.
The chipset can receive and decode up to four channels in parallel, two for FM phase diversity and two for terrestrial digital broadcasting (e.g. DAB). With this feature, the car radio can receive audio content from one channel, while pulling real-time traffic and weather information from another one at the same time.The radio receiver can also seamlessly switch between the analog legacy FM and the digital radio signals and simultaneously demodulate audio and data from two separate digital radio channels (DAB 1.5).
The chipset delivers superior real-time performance without bottlenecks in the baseband processing, coupled with low current consumption and minimized electromagnetic interference. It supports the DAB family of standards (DAB/DAB+/DMB-A), the Digital Radio Mondiale open broadcasting standard, as well as the HD Radio technology (when combined with an external co-processor).
