MC13028A - C-QUAM AM STEREO ADVANCED WIDE VOLTAGE IF and DECODER

General Description

Stereo Threshold Adjustment Pin The function of this circuit is to provide the freedom to achieve a desired value of incoming IF signal level which will cause full stereo operation of the decoder.

Key Features

  • include a signal quality detector that analyzes signal strength, signal to noise ratio, and stereo pilot tone before switching to the stereo mode. A “blend function” much like FM stereo has been added to improve the transition from mono to stereo. The audio output level is adjustable to allow easy interface with a variety of AM/FM tuner chips. The external components have been minimized to keep the total system cost low.
  • Adjustable Audio Output Level.
  • Stereo Blend Function.
