Crystals

Crystals are used in many everyday applications, from communications circuitry and consumer electronics, to precision timing mechanisms in watches and clocks. The 445A2XJ12M00000 is a crystal specifically designed for very high frequency applications, such as cell phones, personal communications systems and satellites. In this article we will discuss the applications and working principles of this crystal.

Application Field

The 445A2XJ12M00000 crystal is designed for radio-frequency applications with frequencies in the UHF range (300-3000MHz). It is suitable for use in a variety of devices that require precise frequency control in this range. For example, it is used in modern cell phones to generate the timing signals used in mobile communications. It can also be used in personal communications systems, satellites, and other applications that require accurate frequency control over a wide range.

The crystal is also widely used in consumer electronics such as televisions, stereos, and home theater systems. It is used in these devices to generate oscillator frequencies for synchronization of video and audio signals.

Working Principle

The 445A2XJ12M00000 crystal works on a principle of resonance. It consists of a quartz plate with a metal electrode on both sides, which is then cut into the shape of a tuning fork. When an alternating voltage is applied to the electrodes, the crystal starts to vibrate at a very precise frequency. This frequency is determined by the geometry and material variability of the quartz plate. This frequency determines the exact frequency of the output waveform of the crystal.

The stable frequency output of the crystal is used as a reference signal in many types of devices, such as cell phones and other radio-frequency generators. It helps the device to keep time accurately and to synchronize signals correctly. The stability of the output frequency of the 445A2XJ12M00000 crystal makes it an ideal component for precision timing and synchronization applications.

Conclusion

The 445A2XJ12M00000 crystal is a very versatile component that is used in a variety of radio-frequency applications. It is especially well-suited for applications requiring precise frequency control in the UHF range. Its stable frequency output makes it an ideal component for timing and synchronization applications in consumer electronics and communication devices.
