Working principle

402F3601XIJT oscillator consists of an oscillator and a control circuit. The oscillator is a quartz oscillator with a frequency determined by the quartz crystal. The control circuit is used to regulate the frequency of the oscillator signal. The oscillator generates a sinusoidal signal that is amplified and then output via the control circuit.

In addition, the device also has a frequency hopping mode, which is used to adjust the oscillator frequency automatically. The control circuit provides an adjustable low-pass filter for the oscillator to reduce the amplitude of the low-frequency noise and provide a stable reference frequency signal.

Finally, by detecting the output frequency of the quartz crystal oscillator and comparing it with an accurate reference frequency, the control circuit adjusts the frequency of the output signal from the quartz crystal oscillator to realize a precise frequency control.
