TEA5767 FM Radio Module

The TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage applications with fully integrated Intermediate Frequency (IF) selectivity and demodulation. The radio is completely adjustment-free and only requires a minimum of small and low cost external components. The radio can be tuned to the European, US, and Japanese FM bands.FeaturesHigh sensitivity due to integrated low-noise RF input ampliå¥ÌâåerFM mixer for conversion to IF of the US/Europe (87.5 MHz to 108 MHz) and Japanese(76 MHz to 91 MHz) FM bandPreset tuning to receive Japanese TV audio up to 108 MHzRF Automatic Gain Control (AGC) circuitLC tuner oscillator operating with low cost å¥Ìâåxed chip inductorsFM IF selectivity performed internallyNo external discriminator needed due to fully integrated FM demodulatorCrystal reference frequency oscillator; the oscillator operates with a 32.768 kHz clockcrystal or with a 13 MHz crystal and with an externally applied 6.5 MHz referencefrequencyPhase-locked loop (PLL) synthesizer tuning systemI2C-bus and 3-wire bus, selectable via pin BUSMODE7-bit IF counter output via the bus4-bit level information output via the busSoft muteSignal dependent mono to stereo blend [Stereo Noise Cancelling (SNC)]Signal dependent High Cut Control (HCC)Soft mute, SNC and HCC can be switched off via the busAdjustment-free stereo decoderAutonomous search tuning functionStandby modeTwo software programmable portsBus enable line to switch the bus input and output lines into 3-state mode
