FM Receiver

FM Receiver
* General Description
This is a single-chip electronically tuned FM stereoradio for low-voltage application with fully integratedIF selectivity and demodulation. The radio is completelyadjustment-free and only requires a minimum of small andlow cost external components. The radio can be tuned tothe European, US and Japanese FM bands.
* Features
- High sensitivity due to integrated low-noise RF input amplifier- FM mixer for conversion to IF of the US/Europe (87.5 to 108 MHz) and Japanese (76 to 91MHz) 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
- PLL synthesizer tuning system- I2C-bus and 3-wire bus, selectable via pin BUSMODE- 7-bit IF counter output via the bus- 4-bit level information output via the 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 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- Automotive temperature range (at VCCA, VCC(VCO) and VCCD = 5 V).
