NXP Semiconductors N.V. has introduced its next-generation FM car radio receivers for background scanning and data services. The TEF7006 and TEF7007 can decode data from Radio Data Systems (RDS), Radio Broadcast Data System (RBDS) and Traffic Message Channel (TMC) services, enabling the devices to offer unique infotainment and radio station data to consumers, NXP said.

Designed specifically for the automotive market, the devices deliver higher performance compared to alternative automotive solutions based on consumer or mobile designs, NXP claimed. Built on NXP's technologies in 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, low-cost design, the company said.

The devices cover a broad band spectrum from 76 to 108MHz, used across Europe, Japan and the U.S. 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 0.85mm, requiring minimal external components.

"As an on-board tuner solution, which reduces the PCB area, lowers costs and offers superior performance compared with conventional module solutions, the TEF7006 is a great fit in our product portfolio for car OEMs," said Yukihiro Hashimoto, general manager of the reception system engineering department at Fujitsu-Ten, Japan. "The device can be applied flexibly in many products, covering a wide range of FM reception standards and offering various interfaces such as MPX output and digital audio output. As RDS/TMC functionality is already a mandatory requirement in the European market, at Fujitsu-Ten we are convinced that the TEF7006 strengthens our future product roadmap by delivering an integrated system solution with NXP's existing automotive DSPs."

The TEF700x can be used in conjunction with NXP's digital low-IF car Digital Signal Processing (DSP) systems for radio/audio applications. The reception quality and performance are similar to that of the main tuner, and therefore optimized 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.

The TEF7006 and TEF7007 are currently available for purchase.
