SIT8021AI-J4-XXS-19.200000E

Oscillators are electronic circuits that generate an electrical signal at a certain frequency, producing a periodic effect. This energizes a component within an electronics system to operate in a periodic or cyclic fashion. The SIT8021AI-J4-XXS-19.200000E oscillator fits in this designation and has multiple applications and a working principle that aids its purpose.

Applications

The SIT8021AI-J4-XXS-19.200000E oscillator has many applications, from telecommunications to computers and other digital equipment. It is a quartz crystal oscillator that can be used for clock timing in various devices such as in the timing of memory controllers, microprocessors, and audio/video electronics. It also provides a stable steady state frequency which is seen as a superior clocking source for supervisory circuits, such as those employed in data communication networks. This oscillator is also used as an audio generator and is well suited to applications that require a low-power, low-noise oscillator.

Working Principle

The SIT8021AI-J4-XXS-19.200000E oscillator is a quartz crystal-based oscillator, which uses the resonance of a quartz crystal within the unit to oscillate an electric signal when connected to a circuit of suitable components. The frequency of this oscillation typically lies within the range of 1 Hz to 50 MHz and is determined by the frequency of the quartz crystal. The circuit of the oscillator includes an amplifier and an RC or LC timing network, that is used to provide impedance matching and stability to the frequency of the electric signal.

The principle of the crystal oscillator revolves around the resonance of the crystal and its ability to vibrate in an exact frequency when a suitable voltage is applied. When the crystal is perfectly symmetric, it has an equal number of negative and positive ions on its surface. These ions create an electric field, which causes the surface of the crystal to vibrate in response to an electric signal. The frequency of this vibration will match the frequency of the crystal, which is determined by both its physical properties and its internal structure. If the voltage applied is greater than the frequency needed, the crystal will reset and start to vibrate again, resulting in a consistent electric signal.

Due to its ability to generate a consistent, stable frequency, the SIT8021AI-J4-XXS-19.200000E oscillator is widely used in multiple applications, from telecommunications to computers and other digital equipment. Its design also allows it to provide a reliable clocking source for supervisory circuits, providing a low-power, low-noise oscillator.
