Oscillators

Oscillators are a type of electronic circuits used to generate a repetitive waveform. In this article, we’ll explore the application field and working principle of the 353WB5A426T oscillator.

Application Field

The 353WB5A426T oscillator is a quartz-based, low-frequency, high-stability oscillator. It is mostly employed to provide a stable reference frequency for timing control circuits. It is especially suitable for applications requiring high levels of performance, accuracy, and stability. The 353WB5A426T can be used, for example, in telecommunications networks, server systems, industrial electronics, radars, and navigation systems. The 353WB5A426T has the following characteristics: frequency range of 32.768kHz to 1.5MHz, temperature range of -40 to +85 degrees Celsius, stability less than +/-25 ppm, aging rate less than +/-5 ppm per year, output voltage of 1.8V to 5V.

Working Principle

The 353WB5A426T oscillator works by employing the piezoelectric effect, whereby electricity is generated through the deformation or vibration of certain crystalline materials such as quartz. A quartz crystal is contained inside the oscillator\'s casing, and is connected to two metal plates, which in turn are connected to electrodes. When a voltage is applied to the electrodes, the quartz crystal is forced to vibrate at a very precise frequency. The frequency of the quartz crystal vibration will depend on its size, shape, and cut angle; with the 353WB5A426T, the frequency range is 32.768kHz to 1.5MHz. The vibrating quartz crystal interacts with the two metal plates, which act as electromechanical transducers, selectively amplifying the signal generated by the vibrations. This amplified signal is then sent to a voltage control amplifier and finally to the output pins of the oscillator.

Conclusion

The 353WB5A426T oscillator is an important component for many applications requiring precision timing control. It works on the basis of the piezoelectric effect, whereby electricity is generated through vibration of inherent quartz crystals. Depending on its size, shape, and cut angle, the quartz crystal vibrates at a very precise frequency. The amplified signal generated by the vibrations is then sent to a voltage control amplifier and finally to the output pins of the oscillator.
