What is a crystal?

Introduction: Crystal oscillator refers to cutting a slice (abbreviated as a wafer) from a quartz crystal at a certain azimuth. A quartz crystal resonator is abbreviated as quartz crystal or crystal and a crystal oscillator. The products are generally packaged in metal enclosures and are also available in glass, ceramic, or plastic packages.

The role of the crystal oscillator is mainly the following, one is used in various circuits to generate oscillation frequency; the other is used in conjunction with other components to generate a standard pulse signal in a digital circuit, which is a special kind of small The crystal oscillator is called a quartz crystal resonator for clock pulses. The quartz crystal oscillator is a high-accuracy and high-stability oscillator and is widely used in various types of oscillation circuits such as color TVs, computers, remote controllers, etc., as well as frequency generation in communication systems. The device generates a clock signal for the data processing device and provides a reference signal for a specific system; there is also a clock quartz crystal oscillator that is used on a timepiece.

With the development of high-tech and portable technology such as computers, the development trend of crystal oscillators has also changed. For example, its packaging has changed from the traditional bare metal outer covering plastic metal to the ceramic package, which has greatly reduced the size of the crystal oscillator. At the same time, due to its functional needs, another significant increase in efficiency is high frequency and low noise, such as the use of GPS is not allowed to have frequency fluctuations, so this will further strengthen the function of Spherical Crystal.

Of course, with different needs, more and more crystal oscillators are classified, such as quartz crystal devices, temperature-compensated crystal devices, voltage-controlled crystal devices, and so on, which are not described in detail here. With the development of networks, crystal oscillators The scope of application will be wider and wider and its technology will be further improved. Hengyi Hong Kong Enterprise Co., Ltd. was established in 2003. It is a high-tech enterprise specialized in R&D, production and sales of quartz crystal products. The domestic production plant was founded in 1996 and has accumulated rich experience in production technology for many years. With complete frequency, stable electrical performance and moderate product prices, it can produce 30 million crystal products annually. The company's products are mainly used in: all kinds of host boards, set-top boxes, modems, MP3, MP4, U disk, car audio, GPS, WIFI, driving recorder, head-up display, LED controller, remote control toys and mobile phones.
