The picture shows the frequency Synthesizer circuit which is composed of MSM5820RS. The circuit uses 400HZ as center and it realises ±10% frequencyregulation by adjusting FP1's resistance value. S1 is reset switch. The oscillating circuit of 2MHz which is composed of TC5082P and crystal will output frequency signal of 500KHZ through pin 5 after it is frequency divided by TC40H074P. The signal will be put on MSM5820RS's pin 27 and then it will output signal from pin 6.
