描述 Description

This circuit is a complete one-chip full-feature AM stereo decoding and pilot detection system. It employs full-wave envelope signal detection at all times for the L + R signal, and decodes L– R signals only in the presence of valid stereo transmission.● No Adjustments, No Coils
● Few Peripheral Components
● True Full-Wave Envelope Detection for L+ R
● PLL Detection For L–R
● 25 Hz Pilot Presence Required To Receive L– R
● Pilot Acquisition Time 300 ms For Strong Signels, Time
  EMended For Noise Conditions To Prevent “Falsing”
● Internal Level Detector Can Be Used As AGC Source ., ~.m~.l:.’ ,
