Order this document by MC13020/D MC13020 Motorola C-QUAM® AM Stereo Decoder This circuit is a complete one ship, 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 Signals, Time Extended for Noise Conditions to Prevent “Falsing” • Internal Level Detector can be used as AGC Source MOTOROLA C–QUAM® AM STEREO DE...
