FM receivers bring background scanning and data services to car radios

NXP has introduced the TEF7006 and TEF7007, its next generation of FM car radio receivers for background scanning and data services.  These receivers are able to decode data from Radio Data Systems (RDS), Radio Broadcast Data System (RBDS) and Traffic Message Channel (TMC) services.

Built on NXP’s low-IF tuners, car DSPs and digitally processed RDS demodulation and decoding technology, the new FM receivers enable a rich infotainment experience via radio broadcast data, delivering automotive-qualified performance in a compact design.
The globally compatible devices cover a broad band spectrum from 76 to 108 MHz, used across Europe, Japan and the US. The receivers are designed for easy integration and are available in a thin leadless HVQFN plastic package with a body size of 5 x 5 x 0.85-mm, requiring minimal external components.
The TEF700x can be used in conjunction with NXP’s digital low-IF car DSP systems for radio/audio applications. The reception quality and performance are similar to that of the main tuner, and therefore optimised for background receiver functions.
Both devices can also operate as standalone TMC receivers in navigation units or be used in Traffic Information Messages (TIM) recording applications. The TEF7007 also adds an integrated FM antenna buffer to simplify the development of systems that require buffering.
