FM radio tuner great for adding FM radio to your electronics projects.

n High sensitivity due to integrated low-noise RF input ampli?er n FM mixer for conversion to IF of the US/Europe (87.5 MHz to 108 MHz) and Japanese (76 MHz to 91 MHz) FM band n Preset tuning to receive Japanese TV audio up to 108 MHz n RF Automatic Gain Control (AGC) circuit n LC tuner oscillator operating with low cost ?xed chip inductors n FM IF selectivity performed internally n No external discriminator needed due to fully integrated FM demodulator n Crystal reference frequency oscillator; the oscillator operates with a 32.768 kHz clock crystal or with a 13 MHz crystal and with an externally applied 6.5 MHz reference frequency n Phase-locked loop (PLL) synthesizer tuning system n I 2C-bus and 3-wire bus, selectable via pin BUSMODE n 7-bit IF counter output via the bus n 4-bit level information output via the bus n Soft mute n Signal dependent mono to stereo blend [Stereo Noise Cancelling (SNC)] n Signal dependent High Cut Control (HCC) n Soft mute, SNC and HCC can be switched off via the bus n Adjustment-free stereo decoder n Autonomous search tuning function n Standby mode n Two software programmable ports n Bus enable line to switch the bus input and output lines into 3-state mode
