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.
