Oscillators

An oscillator is a device used to generate an alternating current. It is designed to produce an alternating signal that is accurate and stable, free from harmonics or noise distortion. An oscillator is most often used to stabilize a circuit, provide timing signals, or generate a precise frequency. The most common oscillator is the crystal oscillator which uses crystal quartz as the frequency standard. Other types of oscillators include those based on RC networks, LC or tuned circuits, RLC networks, and vacuum tubes.

Working Principle

KX2511B0032.768000 oscillators use the quartz crystal as its frequency standard. The piezoelectric effect is used for quartz crystal to cut out a frequency of oscillation as the oscillator’s frequency. It is due to the vibration of the crystal reels which form an electric signal with the same frequency. It allows the quartz to be cut in certain way to make an oscillator with identical frequency.

The shearing action and resonating properties of quartz crystal allow the spark gap to shove the electrons back and forth across the short circuit. This will, in turn, generate a voltage wave with the same frequency as the gap between the electrodes. The frequency of the oscillator will be determined by the size and shape of the crystal.

In the process of frequency generating, quartz crystal will cause the voltage across its electrodes to be slightly higher than that of the voltage waveform. This will allow the electrons in the gap to continue with the voltage across the quartz, further reinforcing the feedback loop.

The oscillator will provide current output rather than voltage output, and the resonant frequency of the oscillator will be determined by the size and shape of the crystal. Thus, the crystal oscillator can be very accurate and stable since its frequency can be precisely tuned and controlled.
