FM IF System

General Description\nThe LM3189N is a monolithic integrated circuit that provides all the functions of a comprehensive FM IF system. The block diagram of the LM3189N includes a three stage FM IF amplifier/limiter configuration with level detectors for each stage, a doubly balanced quadrature FM dete ■ Exceptional limiting sensitivity: 12 μV typ at -3 dB point\n■ Low distortion: 0.1% typ (with double-tuned coil)\n■ Single-coil tuning capability\n■ Improved (S + N)/N ratio\n■ Externally programmable recovered audio level\n■ Provides specific signal for control of inter-channel muting (squelch;
