Working Principle

The SIT9120AC-2B3-33E125.000000Y oscillator is based on a Pierce-type oscillator design. Its core is formed by an active device, such as a transistor, and two capacitors. The output frequency is determined by the parameters of the active device and the values of the two capacitors.The active device acts as a switch that controls the voltage on the capacitors. When the voltage on one of the capacitors falls below a certain threshold, the switch is turned on and the capacitor is charged again. This process is repeated repeatedly, with the capacitor voltage oscillating from a high to a low level and back again. This creates an oscillatory output signal at the frequency determined by the active device parameters and the capacitors.

Conclusion

In conclusion, the SIT9120AC-2B3-33E125.000000Y oscillator is a versatile device that is used in many applications. Its robust performance makes it suitable for precision timing and frequency reference applications, as well as consumer audio, military and medical applications.
