Crystals: LFXTAL017145BULK Application Field and Working Principle

Crystals are widely used in many kinds of electronics and instrumentation, ranging from medical and industrial equipment, to personal computers and mobile communications. The LFXTAL017145BULK crystal is a popular choice for crystal oscillators and can be found in a wide range of applications. This article will discuss the application field and working principle of the LFXTAL017145BULK crystal.

Application Field

The LFXTAL017145BULK crystal is well-suited for use in frequency-controlled applications due to its high stability. It is particularly well-suited for use in communications systems as its frequency can be adjusted precisely with a frequency divider to ensure the transmission of digital signals. It is also widely used in crystal oscillators for the generation of timing signals. It can also be used in a wide range of metrology and measurement systems to provide an accurate reference for the calibration of other instruments.

Working Principle

The working principle of the LFXTAL017145BULK crystal involves the use of piezoelectric effect. When an electric field is applied to a piezoelectric material such as quartz, it is subjected to a mechanical strain which causes it to vibrate at a very high frequency. This frequency is then stabilized by an electrical circuit connected to the crystal. The size and shape of the crystal determines the frequency of vibration, so the frequency of the generated signal can be easily adjusted by changing the size and shape of the quartz element.

The frequency of the quartz crystal oscillator is determined by the oscillation frequency of the quartz, which is also known as the "threshold" frequency. The threshold frequency is affected by temperature, pressure and mechanical shock, so the oscillation frequency needs to be periodically recalibrated to ensure accuracy. This is done by measuring the frequency with an oscilloscope, and then adjusting the frequency with the help of a frequency divider or multiplier.

Conclusion

The LFXTAL017145BULK crystal is an ideal choice for frequency-controlled applications due to its high stability. Its piezoelectric properties enable it to generate a stable, frequency-adjustable output which can be used in a wide range of metrology and measurement systems. The frequency of the quartz crystal oscillator is easily adjusted by changing the size and shape of the quartz element, and the frequency can also be re-calibrated by using a frequency divider or multiplier.
