TEF668X
Low IF tuner high performance one-chip
Rev. 1 — 30 July 2013
Product short data sheet
1. 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.

3. Applications
The TEF668X is a single tuner AM/FM receiver for automotive applications and supports
analog AM/FM and HD/DRM reception (HD/DRM is supported in TEF6688 only).
Additionally, due to a common technology platform, the TEF668X can be combined with
TEF701X, SAF775X and SAF360X for optimal system application through common
crystal oscillator sharing.
