Working Principle

The SIT1618BE-23-33E-12.000000D oscillator works on the principle of negative feedback. It incorporates a quartz crystal made of two electrodes set on a quartz substrate, and it is this quartz substrate which gives the oscillator its stability. The oscillator creates a continuous sinusoidal waveform by drawing electrical energy from the quartz crystal, where electrons are passed back and forth along the crystal continuously. This process is called oscillation.

The oscillator is built on a hybrid oscillator circuit which consists of a crystal oscillator, capacitors, and microresonator. The crystal oscillator is fed with an alternating current of a specific frequency and an external capacitor is used to set the frequency of the oscillator. This capacitor acts as a frequency discriminator which detects any drift in frequency. When frequency drift occurs, the capacitance of the capacitor is changed to match the crystal oscillator’s frequency and hence the output frequency remains stable over time and temperature variations.

It is this frequency stability which makes the SIT1618BE-23-33E-12.000000D an ideal choice for RF and communication systems. The combination of the crystal oscillator, the capacitor and microresonator ensures a stable frequency in the event of any fluctuations in temperature or process variations. This makes the SIT1618BE-23-33E-12.000000D a superior option to other oscillators in terms of performance.

Conclusion

The SIT1618BE-23-33E-12.000000D quartz crystal oscillator is a precise and stable electronic oscillator designed to generate clock signals of very high accuracy and long-term stability. It is suitable for a wide range of applications in RF and communication systems, automotive, industrial, and consumer electronics.
