NXP FM-RDS/TMC background receivers TEF7006 & TEF7007 Key features ► Compact, highly integrated, and pin-compatible devices ► Lowest total system cost when combined with other NXP offerings - Low-IF DSP family SAF774x - High-efficiency, one-chip radio family TEF663x ► Support standalone operating mode with quartz crystal ► Fast-mode I2C bus (400 kHz) ► Single 5 V supply voltage ► AEC-Q100 qualified ► HVQFN32 package (5 x 5 x 0.85 mm, 0.5 mm pitch) The NXP TEF7006 and TEF7007 deliver automotive-qualified performance while enabling compact, low-cost implementation of FM-RDS background receivers. They perform all the radio and audio functions, building on NXP's market-leading technologies for low-IF tuners and digital low-IF car DSPs, and digitally processed RDS demodulation and decoding based on NXP's proven technology. The TEF7007 adds an integrated FM antenna buffer, to simplify the development of systems that require buffering. Both devices are completely adjustment-free and require only a small number of external components. The very high level of integration makes it easy to obtain a very compact design. The FM receivers in both devices cover the Japan/EU/USA bands from 76 to 108 MHz and are able to decode data from Radio Data System (RDS), Radio Broadcast Data System (RBDS), and Traffic Message Channel (TMC) services. DARC/VICS decoders are supported as well, via the MPX output. Excellent tuner characteristics, along with the ability to detect all relevant weak signal conditions, make it possible to use these devices as equivalent receivers for background station list generation and updates. The devices can be used in combination with NXP's digital low-IF car DSP systems (TEF7000 & SAF774x) for car radio/ audio applications. They can interface to the car DSP clock reference, or can use a crystal oscillator operating at 16 MHz. 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 in Traffic Information Message (TIM) recording applications. output, and also at digital I²S-bus audio interface. That way, both interfaces can support either TIM recording devices that use analog or digital inputs. Both devices use an on-chip, highly linear and AGC-controlled FM LNA and mixer for best image rejection. In combination with a fast PLL tuning system, which controls a fully integrated low-phase-noise VCO, the desired FM signal is converted to a complex 250 kHz IF. To...
