402F1921XIDT application field and working principle

Crystals can be found in many different products, from watches and clocks to electrical components and medical equipment. The 402F1921XIDT crystal is specifically used in frequency control for electronic and electrical devices. This type of crystal is manufactured using a dielectric material, typically quartz, and with cavities, known as slits, running along the length of the crystal.

The 402F1921XIDT is capable of producing output frequencies in the range of 12.5–60 MHz and has stability ratings of ±5ppm at 25℃, ±20ppm at −20℃ to +70℃, and ±50ppm at −40℃ to +85℃.

Applications

The 402F1921XIDT crystal is most often used in applications that require accurate frequency measurement, in particular applications where a stable frequency is essential. Examples of such applications include cellular phones, two-way radio communications, satellite navigation systems and other global positioning systems.

The 402F1921XIDT crystal can also be used in industrial applications, in automotive applications and for telemetry systems, as well as for communication interface circuit applications.

Operation

The operation of the 402F1921XIDT crystal is based on the fact that quartz is piezoelectric, which means it can be deformed when a voltage is applied to it. As the crystal is deformed, it vibrates at a frequency determined by its size and dimensions. When the voltage applied to the crystal is removed, the crystal resumes its original shape and stops vibrating.

The 402F1921XIDT crystal is connected to an electronic circuit, which is used to control the frequency of vibration of the crystal. This allows for accurate and stable frequency measurements. The 405F1921XIDT crystal is typically used in clock circuits and oscillators, as well as in digital frequency counting circuits.

Conclusion

The 402F1921XIDT crystal is a type of quartz crystal that is used for frequency control in electronic and electrical devices. It has a frequency range of 12.5–60 MHz and stability ratings of ±5ppm at 25℃, ±20ppm at −20℃ to +70℃ and ±50ppm at −40℃ to +85℃.
