What are the crystal package methods?
For the crystal oscillator, there are different ways in the process of crystal package, such as in-line type, patch type and so on. When we are understanding, we need to divide according to different series, and for the in-line packaging method, there are different subdivisions in this way. When we understand, we can understand according to the so-called device configuration.
Some professional technicians will also consider the size of the crystal oscillator when it comes to understanding. In fact, for ordinary plug-ins, the shape is various, and the crystal package also needs different shape design, so in this respect, you can follow The volume is divided. In addition, for an oscillator, which is called an electromechanical device with a stable frequency, it is required to be widely used in communications, broadcasting, and the like when operating.
First, in-line
For this kind of crystal package, it is mainly for the cylindrical crystal series, and it can also be divided into 49S series and ceramic series. For quartz crystals, there is a fixed requirement for the oscillator frequency adjustment. In order to ensure that the selection frequency is uniform, for the application range, settings need to be given according to different application directions, such as carrier communication, broadcast media, etc. This aspect is the same.
Second, patch
This is a very common packaging method. In the process of subdivision, there are also many, such as 2520, 6037, etc. For such plug-ins, the full size is large and small, we can according to the high type. The difference from the low type is given. Of course, it is also possible to refer to the information of the foot position. In this respect, the full-size shape can include two types, which are a rectangle and a square. It is worth noting that for the inside of the oscillator, the IC's pin count also represents a square, which is called 4PIN.
According to the classification of the above crystal package, we also need to divide according to different application angles. When the ordinary crystal and the temperature-compensated crystal oscillator are packaged, they can also be classified according to the shape. Generally speaking, the most common way is rectangular. DIP14 type, etc., when the signal is generated, it can ensure that the signal is repeated continuously, thus achieving a stable output frequency.
Through the above introduction, we should understand the crystal package method, in the process of timing setting, we can apply according to the requirements of the current microcontroller, so as to improve the speed of the oscillator and ensure the internal timing code setting is more Clearly, then in the process of application, the crystal can truly ensure the information transmission of the sine wave, making the signal transmission repeat and effective.
