Crystals: 402F48011CAT Application Field and Working Principle

Crystals are widely used in electronics, communications, defense, aerospace, instrumentations, medical and other fields of science and technology. As a special type of crystal, the 402F48011CAT has been drawing more and more attention due to its high frequency stability, wide temperature range and great performance. In this article, we are going to learn more about the application fields and working principle of 402F48011CAT crystal.The 402F48011CAT crystal is a highly frequency stable crystal oscillator which works in a wide range of frequencies that including 6.144 MHz, 8.103 MHz, 10.738 MHz, 15.36 MHz, 20.443 MHz, 24.995 MHz and other frequencies. It has a small size and offers a wide operating temperature range from -40 to +85 °C. The maximum frequency offset of the frequency throughout a temperature range is just ±2 ppm and its stability rate is incredibly lower than its predecessors. The wide temperature range and the frequency stability of the 402F48011CAT makes it the crystals of choice when it comes to various applications that require extreme accuracy and reliability. Some examples of the applications of the crystal are radio base stations for mobile communication, military radio communication and satellite radio-navigation systems. The crystal is also used in computers and other digital devices to provide accurate timing signals for digital circuits.The working principle of 402F48011CAT crystal is based on the fact that if a crystalline material like quartz is cut along specific crystalline axes and is mechanically hand tuned, it will vibrate at a fixed frequency. This is because quartz has the ability to vibrate at fixed, predefined frequencies when it is in the form of crystalline structure. The frequency of vibration of the quartz can be determined if the physical characteristics of the quartz such as its shape, size, and directionions of cut are kept constant.The frequency of vibration of the quartz can be externally controlled by connecting it in an electrical circuit. When an external electrical signal is applied to the crystal oscillator, it vibrates at the same frequency as the external signal. And by changing the oscillator circuit, the frequency of the signal can be adjusted and the frequency stability of the crystal oscillator can be improved.The 402F48011CAT crystal is connected to an oscillator circuit to generate very precise and stable frequency signals. The oscillator circuit consists of two basic components, namely the crystals and the circuitry that includes resistors, capacitors and transistors. The circuit is tuned so that when the crystal vibrates, the circuit operates at the required frequency. The output signal of this circuit is then amplified to drive the output circuit.To ensure that the 402F48011CAT crystal works perfectly in all conditions, it can be packaged or sealed in a strictly controlled environment to maintain an optimum temperature and humidity level. This ensures that any variations in the environment does not affect the frequency of the crystal\'s oscillations.In conclusion, the 402F48011CAT crystal is a highly frequency stable crystal oscillator used in various applications such as radio base stations and computers. Its wide temperature range and frequency stability makes it well suited in applications that require extreme accuracy and reliability. Its working principle is based on the fact that a crystalline structure can vibrate at fixed, predefined frequencies and this frequency can be externally controlled by connecting it in an electrical circuit. The oscillator circuit consists of two basic components, namely the crystals and the circuitry and the output signal of this circuit is then amplified to drive the output circuit to maintain the required frequency stability.
