This article will explore the application field and working principle of the 402F480XXCDT.

Application field of the 402F480XXCDT

The 402F480XXCDT is used in a variety of fields, the most prominent being aviation, medical and automotive electronics. The crystal timing is essential for aviation safety and accurate navigation, and the 402F480XXCDT is often used for this purpose. In the medical field, the crystal is used for precise timing in medical and scientific instruments, providing accurate measurement of time-sensitive events such as drug reactions or biomedical tests. In automobiles, the 402F480XXCDT crystal is used for navigation, fuel and oil levels, diagnostics, automatic emergency systems, and more.

Working Principle of the 402F480XXCDT

The 402F480XXCDT is a quartz crystal oscillator, and its working principle is based on the piezoelectric effect. A quartz crystal is made up of quartz crystals in a three-dimensional matrix, which when connected to an electric circuit, will vibrate at a constant frequency. When the frequency signal is sent to oscillating circuit components, it creates an electronic frequency. The crystal will then transfer this signal to the connected oscillator, setting and controlling the timing of the oscillator signal.

The 402F480XXCDT crystal is composed of a high-frequency crystal oscillator, a quartz crystal resonator, and other components such as capacitors, transistors and integrated circuits. The quartz crystal resonator is connected with the capacitor and the transistor in an oscillating circuit, forming an LC circuit. The quartz crystal oscillator itself is a tuned circuit and acts as an energy storage device. As the LC circuit is driven by the oscillated frequency, the crystal resonates at a certain frequency and the oscillator signal will be at this same frequency.

The quartz crystal can also be used in a temperature controlled crystal oscillator (TCXO), in which a thermistor is used to maintain an ideal frequency over a range of temperatures. The thermistor is connected to the crystal oscillator via an external circuit, providing a temperature correction and enabling greater accuracy. The temperature stability of the 402F480XXCDT enables a more reliable performance at a wider range of temperatures.

Conclusion

The 402F480XXCDT is an invaluable component in many industries, providing accurate timing and enabling a wide range of electronic applications. Its use in aviation, medical and automotive fields ensure a reliable performance, and its temperature stability allows it to operate in different environments. Its working principle, based on the piezoelectric effect, ensures that the crystal is able to remain in tune and oscillate at the same frequency.
