MOTOROLA ANALOG IC DEVICE DATA
The MC13028A is a third generation C–QUAM stereo decoder targeted
for use in low voltage, low cost AM/FM E.T.R. radio applications. Advanced
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.
