405C35D30M00000 Application Field and Working Principle

405C35D30M00000 is a crystal oscillator whose uses mainly include microcomputer and digital circuits, frequency and phase locked loops, as well as telecommunications and general timing, frequency control, and frequency standard instruments. It is made up of a quartz crystal and two leads connected to the crystal.

In order to describe how a crystal oscillator works, we must first understand the relationship between the frequency, wavelength, and period of a wave. Frequency refers to the number of cycles of the wave per unit time, while the wavelength refers to the physical length of one cycle of the wave. The period is the time it takes to complete one cycle of the wave, and is measured in seconds.

Working Principle

The 405C35D30M00000 crystal oscillator works according to the piezoelectric effect. This effect states that when an electrical field is applied to certain materials like quartz, it will cause the material to vibrate at a certain frequency. Consequently, when an alternating voltage is applied to the two leads of the crystal, the crystal vibrates and generates an alternating electrical signal with the same frequency.

This alternating electric signal then passes through a resonant circuit which consists of a capacitor, a resistor, and an inductor. The resonant frequency of this circuit is equal to the frequency of the crystal and is usually much higher than the frequency of the alternating electric signal. As a result, the oscillator amplifies the signal, producing an output signal with a much higher frequency.

Applications

The 405C35D30M00000 crystal oscillator offers a wide range of applications in various fields. As previously mentioned, the oscillator is mainly used in communications, microcomputers, digital circuits, frequency and phase locked loops, and frequency standards. It is also commonly used in television and radio transmitters, as well as electronic watches, clocks, and other precision time instruments. Moreover, it can be used as a reference source in many types of instruments, such as frequency meters, frequency counters, spectrum analyzers, and oscilloscopes. Finally, the crystal oscillator can be used as a variable frequency generator in applications such as motor speed control and power supply switching.
