The Low IF Tuner HIgh performance One chips, TEF6686 and TEF6688, are single-chip radio ICs including an AM/FM radio tuner and software-defined radio signal processing. They extend NXP Semiconductors’ broad, industry-proven car radio single tuner portfolio, offering outstanding radio performance with the widest range of features and state of the art software algorithms at most optimized system costs. Both devices are available in HVQFN packages occupying the smallest PCB space and are suitable for dual- and multi-layer PCBs. The radio receiver includes highest feature sets, the FM/AM front-ends, tuning synthesizer, channel filtering, FM Channel Equalization, FM multipath improvement, demodulation, FM stereo decoding, weak signal processing, noise blanking and RDS and provides an interface to a DARC demodulator/decoder. The TEF6686 and TEF6688 can provide stereo audio in digital format on the I²S outputs and on the audio DAC outputs. The TEF6688 supports the digital radio standards HD Radio and Digital Radio Mondiale (DRM) digital radio when used with NXP Semiconductors’ digital radio coprocessors such as SAF356X and SAF360X.
