The quartz crystal oscillator, which is actually a quartz crystal cut off from the lead, has a very important function, that is, mechanical vibration occurs when the current is energized. When we understand crystal vibrations, we need to compare their materials and properties. For electromechanical equipment, mechanical and electrical effects often occur during operation. What is crystal perk? We can also be analyzed according to important features, such as its coefficient of thermal expansion, the chemical properties of quartz crystals, etc., which directly affect the size and stability of mechanical forces, let us know its application range!
First of all, the electromechanical effect as the electromechanical effect, can be understood as the transformation of electromechanical machines, in fact, in the transformation process, inductors and capacitors can establish some resonant circuits, so that the electric field and magnetic field can promote the rotation of each other. For most lines, it is usually possible to use some resonant circuit to ensure that the power consumption of the quartz crystal is reduced and the Q value is increased.
Second, as an oscillator used its function is to have a healthy functions, and then you can play to the role of the filter, so at work, it's passband curve is very healthy, because it belongs to the quartz crystal, so also belongs to the key elements in the circuit, to provide the reference frequency,, of course, can also play a role of the direct decision.
Third, it is equivalent to a frequency scale as we know it, the mass of the crystal can be estimated by the frequency deviation, which is a very important technical indicator, but in the process of operation, it also involves the specific application scope, which we know usually needs to be configured according to the different types of oscillator. In some cases, it can be used as an oscillator to ensure that the module can avoid vibration and ensure the stability of the suspension. Moreover, at room temperature, electrical components will not be subject to selective interference, so the selection of components and line configuration can be more reasonable and standardized.
Through the above introduction, we should understand what is a crystal oscillator, when we understand, we must first understand the essence of the crystal oscillator, in order to carry out the structure and principle analysis according to its essential characteristics, then can be more comprehensive. Understand its function and function.
