LM1863 AM Radio System for Electronically Tuned Radios
General Description
The LM1863 is a high performance AM radio system intended primarily for electronically tuned radios Important to this application is an on-chip stop detector circuit which allows for a user adjustable signal level threshold and center frequency stop window The IC uses a low phase noise levelcontrolled local oscillator Low phase noise is important for AM stereo which detects phase noise as noise in the L-R channel A buffered output for the local oscillator allows the IC to directly drive a phase locked loop synthesizer The IC uses a ...
