Crystals

Crystal oscillators are an important building block in many electronics circuits. They are used to provide a stable frequency reference, ensuring that various components and devices synchronize properly. As the name implies, crystals are the core of such oscillators.

A crystal oscillator consists of a quartz crystal, electrical circuit and tuning capacitors. The frequency accuracy of the oscillator is determined by the crystal, which vibrates at a precise frequency when an oscillating signal is applied to its electrodes. Thus, the crystal oscillator can provide a stable signal for frequency measurement, synchronization and control.

A typical crystal oscillator design consists of an LC tank circuit and a quartz crystal. The two components are connected in parallel. The inductor of the LC tank circuit forms a resonant circuit, which is tuned with an external capacitance. The quartz crystal is also connected to this circuit, and the frequency of the oscillation is dependent on its physical properties. A quartz crystal has the unique property of exhibiting a change in its electrical properties when voltage is applied to it.

When an oscillating signal is applied to the crystal, it begins to vibrate at its resonant frequency. This vibration, in turn, induces a voltage in the surrounding LC tank circuit, which sustains the oscillation of the crystal. By adjusting the tank circuit’s tuning capacitance, the frequency, or pitch, of the oscillator can be adjusted.

402F19233CAR applications are particularly suited for quartz crystal oscillators, as the stability and accuracy of these oscillators make them ideally suited for precise frequency control. Such applications include radio communication, GPS receivers, broadcast receivers, automotive electronics, medical monitoring, test and measurement equipment, and other systems that require precise frequency control.
