Introduction

The TDA7706M highly integrated tuner is a high/performance AM/FM tuner IC for car-radio applications, suitable for HD Radio reception. It contains mixers and IF amplifiers for AM, FM and WX, fully integrated VCO and PLL synthesizer, IF- processing including adaptive bandwidth control, stereo-decoder, RDS decoder, and digital interfaces for external HD Radio decoding on a single IC. AM/FM IBOC or DRM base band filtering is available in parallel to standard analog reception. The proprietary MuSICA algorithm greatly enhances the FM reception quality under multipath conditions. The utilization of digital signal processing results in numerous advantages: very low number of external components, very small space occupation and easy application, very high selectivity due to digital filters, high customization possibility through software control, automatic alignment and a powerful DSP for custom processing.
