The MC3363 is a single chip narrowband VHF FM radio receiver. It is a dual
conversion receiver with RF amplifier transistor, oscillators, mixers,
quadrature detector, meter drive/carrier detect and mute circuitry. The
MC3363 also has a buffered first local oscillator output for use with frequency
synthesizers, and a data slicing comparator for FSK detection.
