TDA7706
Overview
The TDA7706 highly integrated tuner is a high/performance AM/FM tuner IC for car-radio applications, suitable for HD Radio™ reception.
- FM, AM and weather band reception Fully integrated VCO for world tuning High performance PLL for fast RDS system Integrated AM-LNA and PIN diodes Automatic self alignment for FM front-end preselection filter and image rejection Integrated IF filters with high selectivity, dynamic range and adaptive bandwidth control Drift-free Digital-IF signal processing with high performance RDS demodulation with group and block synchronization High performance stereo decoder with noiseblanker Digital interface for HD Radio™ reception with digital audio blending Fully programmable DSP core I2C bus-controlled I2S input/output digital audio interfaces Single 5 V supply LQFP64 package 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 utilization of digital signal processing results in numerous advantages against today's tuners: 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.
