FM background receiver chips enable cost-effective data functions in car radios
Based on NXPs Low IF tuner technology, car DSPs and digital RDS demodulation and decoding, the TEF7006 and TEF7007 offer comprehensive infotainment functionality. The compact and cost-effective devices are compatible worldwide and cover the frequency range most from 76 through 108MHz. This is the frequency range most used across Europe, the USA and Japan. The FM receiver ICs are offered in a 5x5x0,85mm HVQFN plastic package. According to the vendor, they are easy to integrate into existing and future radio receiver designs and get along with a minimum of external components. In particular they combine well with NXPs existing Dirana range of car radio DSP products.
The TEF700x products can be used in connection with digital Low-IF car DSP systems to create radio and audio applications. Their reception quality and performance are similar to the main tuner, but the new devices are optimized for background functions in that they handle data services instead of audio functions. In addition, both chips can be used as stand-alone TMC receivers in GPS systems or be used to record traffic information. The TEF7007 features an additional integrated FM antenna buffer to ease the design of systems requiring such a buffer.
Both chips are available now. For more information, visit www.nxp.com.
