Working Principle

The SIT1602BI-11-XXN-31.250000E is a very important kind of crystal oscillator, and its working principle is based on the Piezoelectric effect. The main components of the crystal oscillator are a quartz crystal and an electronic oscillator circuit on the external circuit PCB board. The quartz crystal is placed in the external circuit board and fixed with an inner electrode. When an AC signal is applied to it, the quartz crystal will generate a certain strain, electric dipole moment, and thus piezoelectric effect. As a result, a voltage signal will be generated by the crystal. This voltage signal and the feedback resistance of external circuit together form a LC resonance circuit. When the AC signal is applied, the energy of the LC resonance circuit oscillates between the capacitor and the inductor. The quartz crystal inside the oscillator circuit plays the role of a frequency control unit in this process, so that the frequency of the oscillator is stabilized. The output voltage signal of the oscillator is usually a sine wave.
