1 FEATURES ? High sensitivity due to integrated low-noise RF input amplifier ? 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 ? Preset tuning to receive Japanese TV audio up to

108 MHz ? RF Automatic Gain Control (AGC) circuit ? LC tuner oscillator operating with low cost fixed chip inductors ? FM IF selectivity performed internally ? No external discriminator needed due to fully integrated FM demodulator ? 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 ? PLL synthesizer tuning system ? I2C-bus ? 7-bit IF counter output via the I2C-bus ? 4-bit level information output via the I2C-bus ? Soft mute ? Signal 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 I2C-bus ? Adjustment-free stereo decoder ? Autonomous search tuning function ? Standby mode ? Two software programmable ports ? Bus enable line to switch the bus input and output lines into 3-state mode.
