  • The TDA7705 highly integrated tuner (HIT) is a new generation of high performance tuners for carradio applications.

    It contains mixers and IF amplifiers for AM and FM, fully integrated VCO and PLL synthesizer, IF-processing including adaptive bandwidth control, stereo decoder and RDS decoder on a single chip.
    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 flexibility by software control and automatic alignment.

    Key Features

    • I2C/SPI bus controlled
    • High performance stereodecoder with noiseblanker
    • LQFP64 package
    • Single 5 V supply
    • Integrated IF-filters with high selectivity, high dynamic range and adaptive bandwidth control
    • Digital IF signal processing, high performance and drift-free
    • Fully integrated VCO for world tuning
    • AM/FM mixers with high image rejection
    • High performance PLL for fast RDS system
    • Automatic self alignment for preselection and image rejection
    • RDS demodulation with group and block synchronization
    • Integrated AM-LNA and AM-PINDIODE
