LM1863 Product details

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
