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. 2. Features and benefits Alignment free digital receiver including tuner and software-defined radio processing Command based high-level user interface combining high control flexibility with ease of control Read information with device and tuning status, reception quality and RDS data FM receiver with a tuning range of 65 MHz to 108 MHz covering Eastern Europe (OIRT), Japan, Europe and US bands AM receiver covering LW, MW and full SW Fully integrated tuning system with low phase noise and fast tuning FM LNA with AGC FM mixer for frequency conversion to a low IF complex signal AM LNA with AGC, matching active and passive antenna applications AM mixer for frequency conversion to a low IF complex signal (AM SW) High dynamic range IF ADC Digital IF signal processing including decimation, shift to baseband, AGC control, I/Q correction, variable IF bandwidth filtering (PACS) and demodulation FM stereo decoding
