Oscillators

Oscillators refer to devices which can generate a signal with alternating current at a certain frequency without any external power supply, and play an important role in various fields of electrical engineering. One of the oscillators is 353VB3I021T, which has remarkable application field and working principle.

Application Field

353VB3I021T oscillator has wide application. Not only can it help in the development of wireless applications such as WLAN equipment and Bluetooth module, but it also provides a solution for a series of other wireless communication applications including satellite communication, mobile communication, Internet of Things and the like. It is designed to provide the highest precision of stability and signal purity.

Working Principle

The 353VB3I021T oscillator mainly operates on the principle of low-noise quartz-controlled oscillators. Its signal oscillation is achieved by the combination of quartz crystal and capacitance components. The quartz crystal composed of soft crystal material and two leads on the plane will vibrate under the effect of the electric signal. In the meanwhile, the capacitance component is composed of two plates that hold certain charge, which corresponds to the electric field that impresses on the quartz crystal and determines its frequency. When a quartz crystal oscillates, it will generate a fluctuating magnetic field that triggers a feedback signal between the capacitance component and the quartz crystal. The feedback signal then reinforces the original vibration in an iterative process. The frequency of oscillation is not affected by the environment or other factors, instead, it depends on the shape and size of the quartz crystal and capacitance component.

To sum up, 353VB3I021T oscillator is an economical and reliable solution for various wireless communication applications, especially for those requiring precise control of signal quality and stability. Benefitting from its relatively simple structure and working principle, it is widely applied in various fields of electrical engineering.
