Working Principle

A quartz crystal oscillator consists of a quartz crystal, two electrodes, and the circuitry to drive and detect the oscillator\'s output. When an oscillating electric current is applied to the quartz crystal, it vibrates at its fundamental frequency. The quartz crystal\'s fundamental frequency is determined by the mass of the crystal and its mechanical properties, such as its shape and size. This fundamental frequency is usually in the range of 10 to 200 megahertz.

The frequency of the quartz crystal oscillator can be accurately controlled by adjusting the tension of the crystal, which is done by adjusting the relative positions of the electrodes. This tension adjustment creates a mechanical resonance in the crystal that causes it to vibrate at its fundamental frequency. In order to maintain a stable frequency, the tension of the crystal must be maintained at a constant level. This can be done by a variety of methods, such as using a temperature compensation circuit or using a voltage-controlled oscillator.

Quartz crystal oscillators are also capable of producing higher frequencies than their fundamental frequency. These frequencies are known as harmonics and can be generated by increasing the tension of the crystal. By controlling the frequency of the oscillator, the performance and accuracy of the device can be improved.

In order to ensure the accuracy of the quartz crystal oscillator, it must be regularly tested and calibrated. This is because the accuracy of the oscillator can be affected by changes in temperature, humidity, and other environmental conditions. Due to the precision of quartz crystal oscillators, they are often found in very critical applications where accuracy is essential.
