445W35S14M31818 Crystals: Application Field and Working Principle

A crystal is a solid material with symmetrically arranged particles forming a regular, repeating pattern in all three dimensions. Such materials can be used to control or generate signals, or as building blocks for micro-electronic components. Crystals are used in a wide range of devices, from precision timing devices, radios and landline telephone systems, to telecommunications networks and satellites. The 445W35S14M31818 crystal is a quartz crystal developed to meet the needs of precision timing and high-frequency applications. This section will provide an overview of the application field of the 445W35S14M31818 crystal, and explain its working principle.

Application Field

The 445W35S14M31818 crystal is a quartz crystal that is optimized for frequencies up to 420 MHz. It is ideal for applications such as high-speed network data communications, cellular systems, global positioning systems (GPS), remote control and key fob receivers, automotive systems, short range wireless systems, and Bluetooth. It is particularly suited to provide high-precision timing in ultra low-frequency (ULF) applications, such as for ground-air communication systems, military systems, and others that require stabilizing frequencies. Moreover, the 445W35S14M31818 is designed to meet stringent low-jitter and low-phase noise requirements. This means that it is well-suited for applications such as those found in computers and other mobile devices, where digital signals may be transmitted at high speeds and require accurate timing.

Working Principle

The working principle of the 445W35S14M31818 crystal is based on mechanical resonance. In its purest form, a quartz crystal is a monolithic structure formed from a single piece of quartz. The resonator frequency is determined by the fixed, specific size and shape of the crystal. When an alternating electrical current is applied to the quartz domain within the crystal, it begins to vibrate at its resonant frequency – a specific frequency determined by its size, shape and composition. The resonance frequency is theoretically determined by the mass of the quartz crystal and the surrounding forces. However, in practice the resonance frequency can be adjusted by varying either the mass or the tension applied to the crystal. Thus, the working principle of the445W35S14M31818 crystal is based on the principle of mechanical resonance.

Conclusion

The 445W35S14M31818 crystal is a quartz crystal that is optimized for frequencies up to 420MHz. It is ideal for applications such as high-speed network data communications, cellular systems, GPS, remote control and key fob receivers, automotive systems, short range wireless systems, and Bluetooth. Additionally, it is designed to meet stringent low-jitter and low-phase noise requirements, making it suitable for digital applications requiring accurate timing. The working principle of the 445W35S14M31818 crystal is based on the principle of mechanical resonance, whereby the resonance frequency is determined by the mass of the quartz crystal and the surrounding forces.
