Working principle

The SIT8919BE-32-18E-125.003125Y crystal oscillator uses a quartz crystal as its resonator. The crystal is held between two electrodes, which are wired to an oscillator circuit. When an oscillating electric current is applied across the electrodes, the crystal resonates at a frequency determined by its size and shape. The frequency of the output voltage of the oscillator is then determined by this resonance. The oscillator is then tuned by varying the applied voltage. A voltage control voltage divider is included to adjust the amplitude of the tuning voltage, which is then applied to the oscillator circuit. This allows the oscillator to be tuned to within the preset frequency range. Once the frequency is set, the oscillator will remain stable, regardless of temperature or voltage fluctuations.

Conclusion

The SIT8919BE-32-18E-125.003125Y is a reliable and stable quartz crystal oscillator capable of operating over a wide range of temperatures and voltages. Its low level output of noise makes it ideal for applications where accuracy is of paramount importance, such as in digital clocks and radio transmitters and receivers. With its wide range of uses and high-precision capabilities, the SIT8919BE-32-18E-125.003125Y crystal oscillator is an invaluable asset for many projects.
