TEF665X
DSP-based radio tuner one-chip
Rev. 1 — 30 July 2013

Product short data sheet

1. General description
The TEF6657 and TEF6659 are single-chip radio ICs including an AM/FM radio tuner and
software-defined radio signal processing. These devices are the successors to the
industry-proven TEF661X product range, with improved performance and feature set at
lower system cost.
Both devices are available in HVQFN packages occupying only smallest PCB real estate
and are suitable for multi-layer PCBs.
The radio receiver includes the FM/AM front-ends, tuning synthesizer, channel filtering,
FM multipath improvement, demodulation, FM stereo decoding, weak signal processing,
noise blanking, RDS and DARC support.
Stereo audio is provided in digital format on the I2S outputs and on the audio DAC outputs.
The TEF6659 supports the HD Radio and Digital Radio Mondiale (DRM) digital radio
standards when used with NXP Semiconductors’ digital radio coprocessors such as
SAF356X and SAF360X.
