General description

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.
