manufacturer: description:the ceramic resonator of the stereo decoder pll circuit is used as a stop signal detector for am signals. for this purpose, the parallel resonance frequency of the resonator, which is unloaded about 456 khz, is reduced by an internal load capacitor down to 455 khz. therefore, the am if must be 455 khz. the internal loading capacitor is defined by the current through amsadj (pin 9) to gnd. an external resistor is connected between amsadj (pin 9) and gnd. it allows the alignment of the stop signal center frequency. the width of the stop window is typicaly 800 hz. if am search- mode is not activated, the pin is internally pulled to ground. |
