Working Principle of an Oscillator Crystal

An oscillator crystal is a device that uses a quartz crystal as part of its electrical circuit, allowing it to generate a frequency signal. The quartz crystal is the key element in the circuit, since it resonates when it is subjected to an AC voltage of the same frequency. This means that the crystal acts like a resonator, creating a signal that oscillates back and forth at a constant frequency, or oscillation period.

The oscillator crystal works by having an AC voltage applied to it. This AC voltage causes the crystal to vibrate at its natural resonance frequency. The oscillator circuit then starts to resonate, creating an oscillating electrical signal at the same frequency. This signal is then amplified and output as an oscillating voltage.

Advantages of an Oscillator Crystal

An oscillator crystal provides several advantages over other types of oscillators. It is capable of producing a more accurate output frequency, and it is also less susceptible to interference from external sources, such as other radio signals. Oscillator crystals also consume less power than other oscillators, making them ideal for battery-powered applications.

Oscillator crystals are also low-cost and have a long life span. They can remain stable for many years, making them an ideal option for projects that require long-term accuracy.
