  • The TDA7540 is a high performance tuner circuit for AM/FM car radio. It contains mixer, IF amplifier, demodulator for AM and FM, stereodecoder, quality detection, ISS filter and PLL synthesizer with IF counter on a single chip.

    Use of BICMOS technology allows the implementation of several tuning functions and a minimum of external components.

    主要特性

    • FM-PartRF AGC generation by RF and IF detectionI/Q mixer for 1st FM IF 10.7MHz with image rejectionMixer for 2nd IF 450kHzInternal 450KHz bandpass filter with bandwidth control by ISSFully integrated FM-demodulator with spike cancellation
    • StereodecoderPLL with adjustment free, fully integrated VCOAutomatic pilot dependent MONO/STEREO switchingProgrammable ROLL-OFF compensationHigh cut and stereo blend-characteristics programmableDedicated RDS-muteInternal noise blanker with several threshold controls
    • AM-PartWide and narrow AGC generationMixer for 1st IF 10.7MHz, AM upconversionMixer for 2nd IF 450kHz, AM downconversionIntegrated AM-demodulatorAM IF- and audio noise blanking
    • Additional FeaturesVCO for world tuning rangeHigh performance fast PLL for RDS-SystemIF counter for FM and AM with search stop signalQuality detector for level, deviation, adjacent channel and multipathISS (Intelligent Selectivity System) for cancellation of adjacent channel and noise influencesAdjacent channel muteFully electronic alignmentAll functions I2C-Bus controlled
