Oscillators

An oscillator is an electronic circuit that produces regular, repeated pulses of alternating current or voltage. The FXTC-HE73PR-16 MHz oscillator is an example of an oscillator composed of piezoelectric quartz crystal. It is a highly reliable, low-power, high-stability device, capable of operating in temperatures up to 125ºC.

Application Field

The FXTC-HE73PR-16 MHz crystal oscillator is primarily used in aerospace applications that require extreme temperatures and reliability. It can be used for applications such as frequency control, frequency measurement, pulse generation, signal conditioning for data acquisition, and timing for microprocessor control systems. Additionally, the oscillator is used in radio frequency services such as satellite communications, point-to-point radio links, and instrument landing systems.

Working Principle

The quartz crystal within the oscillator vibrates at its own resonant frequency when supplied with an electrical signal. This resonant frequency is determined by the physical structure of the crystal. The quartz crystal is cut in the shape of a "Y" that has four sides or faces. The faces are polished and then electrodes are attached accordingly. The electrical voltage/current supplied to the crystal is converted to mechanical vibration that travels through the crystal in the form of standing waves.

When the standing wave is established, a portion of the wave dissipates in the form of heat. This energy is known as the Q factor. The Q factor determines the damping or stability of the oscillator and is determined by the physical dimensions and construction of the crystal.

The FXTC-HE73PR-16 MHz oscillator has an excellent Q factor compared to other quartz crystals. This results in a highly stable oscillator that can be used in applications requiring the utmost precision.
