Crystaloscillatoren

Crystaloscillatoren, also known as crystal oscillators, are electronic oscillators that use the mechanical resonance of a vibrating crystal to create an electrical signal with a precise frequency. The most common type of piezoelectric resonator used is quartz, due to its stability and predictable behavior. When an electric voltage is applied across a quartz crystal, it deforms due to the piezoelectric effect. Conversely, if the crystal is mechanically stressed, it generates an electric voltage. By incorporating the crystal into an electronic circuit that provides feedback, the crystal can be made to vibrate at its natural resonant frequency. This vibration then generates a stable AC signal at that frequency.

The frequency of oscillation is determined by the physical properties of the crystal, such as its thickness, cut angle, and dimensions. This makes crystal oscillators incredibly accurate and stable compared to other types of oscillators, such as LC oscillators. They are widely used in applications where precise timing is critical. This includes digital watches, clocks, computers, radio transmitters and receivers, and virtually any electronic device that requires a stable reference frequency. Their widespread use is a testament to their reliability, accuracy, and cost-effectiveness in producing precise frequency generation.
