Crystals are widely used in high-accuracy clocks and oscillators, where they act as an electronic circuit element known as an oscillator. This oscillator keeps the rate of an electronic circuit constant, which is essential for measuring time accurately and ensuring the proper performance of electronic and telecom devices. The FA-20H 38.4000MF11L-AJ3 crystal falls into this category of highly accurate oscillators. In this article, we discuss its application field and working principle.

Applications

The FA-20H 38.4000MF11L-AJ3 crystal features a frequency of 38.4 MHz, which makes it suitable for use in radio communication, satellite TV, and military radio systems. It is particularly useful for radio systems where higher frequency accuracy is required, as it can withstand temperature fluctuations and environmental conditions.

The FA-20H 38.4000MF11L-AJ3 crystal is also an ideal choice for mobile handsets and other battery-powered devices. This is due to its low current consumption, which results in minimal battery drainage with long-term use. Additionally, its frequency stability over temperature changes, shock loads, and mechanical stress provides enhanced device performance.

Working Principle

The FA-20H 38.4000MF11L-AJ3 crystal operates on a principle of electrical resonance. It consists of two separate plates made of a dielectric material, such as quartz, and an electrical connection. It works by using the electrical oscillator to create a waveform that propagates through the quartz plate. This waveform is then amplified or attenuated by the opposite plate in opposite phase, creating an interference waveform. This waveform can then be used to create a timing signal for precision clocks and oscillators.

The frequency of the waveform generated by the FA-20H 38.4000MF11L-AJ3 crystal is determined by the size of the quartz plate used. If a plate is too thin, it will vibrate at a faster frequency, while a thicker plate will vibrate at a slower frequency. The resonance effect of the quartz plates will amplify any frequency that it is exposed to, and this is how the FA-20H 38.4000MF11L-AJ3 crystal is able to maintain a constant frequency despite changes in the environment or temperature.

Conclusion

The FA-20H 38.4000MF11L-AJ3 crystal is a highly accurate and reliable crystal oscillator that can be used in a variety of radio communication, satellite TV, and military radio systems. Its low current consumption and frequency stability at varying temperatures, shock loads, and mechanical stress make it ideal for battery-powered devices. It works on the principle of electrical resonance, with the size of the quartz plates determining the output frequency of the waveform when subjected to an electrical oscillator.
