Functional Description

A crystal oscillator, comprising a quartz crystal and other circuit components, is the commonly used frequency control element in modern radio, television and communication systems. When a voltage is applied across the terminals of a crystal oscillator, the quartz crystal vibrates at a frequency determined by its physical characteristics, and generates a train of pulses with a repetitive frequency. These are known as ‘oscillation signals’.

The output signal of a crystal oscillator can be sinusoidal, square wave, rectangular, or triangular, depending on the external configuration of the crystal, and the property of the quartz crystal being used. The external circuit of the oscillator typically consists of signal shaping circuits, amplifiers, and frequency multipliers for amplifying and converting the Pulse into a wide frequency range.

Working Principle

When an alternating voltage is applied across the terminals of a quartz crystal, the crystal vibrates at a natural resonant frequency determined by its size, shape and material composition. This frequency is known as the ‘resonant frequency’. The crystal acts like a band-pass filter, allowing the signal to pass with minimal distortion, and very high frequency stability.

The crystal oscillator works on the principle of resonance. As the quartz crystal is periodically driven from its resting state, the particles in the quartz crystal vibrate at the natural frequency determined by the shape, size, and physical properties of the crystal. A voltage oscillator circuit is connected to the terminals of the crystal, and the input voltage is converted into an oscillating signal that is fed back to the crystal. This phenomena of resonance causes the crystal to ‘ring’ at its natural frequency, by way of the voltage oscillator circuit.
