Crystals

Crystals are precision-crafted components that exhibit specific electronic properties. Used in a wide variety of electronics applications, crystals have been used for decades by engineers to create reliable electronic applications. One such crystal is the ECS-85-S-4, a surface mount piezoelectric crystal that is part of a growing range of specialized crystal components.

ECS-85-S-4 Application Field and Working Principle

The ECS-85-S-4 is a surface mount piezoelectric crystal that features a unique ceramic sandwich structure which helps to ensure a high level of stability and excellent frequency stability. It is commonly used in a variety of consumer, industrial and commercial applications. As a surface mount component, the ECS-85-S-4 is easily integrated into a variety of different systems and products.

In terms of its operation, the crystal works by utilizing a two-port resonator driven by an input signal. The two-port resonator is comprised of two piezoelectric elements that reside in a compensation cavity. The input signal, typically in the form of an AC signal, is then used to drive the piezoelectric elements and the resonator vibrates at the fundamental frequency of the crystal which is determined by the size and shape of the crystal. The vibration of the resonator generates an output signal that is at the same frequency as the resonator and this signal is used to drive other components in the system. This type of operation is referred to as a relaxation oscillator.

The crystal can also be used in other oscillator arrangements such as phase-locked-loop (PLL) and voltage controlled oscillator (VCO) configurations. In these cases, the crystal is typically used to maintain the frequency of the signal, while signal conditioning components are used to maintain the phase and voltage of the signal.

The ECS-85-S-4 is an ideal choice for a wide range of applications where accurate, stable frequency oscillations are required, such as in radio frequency systems, satellite communication systems, navigation systems, television receivers, and cellular phones. Due to its small size and high level of stability, the ECS-85-S-4 is an excellent choice for portable electronic devices such as tablets and mobile phones.

Conclusion

The ECS-85-S-4 surface mount piezoelectric crystal is an excellent choice for providing stable frequency oscillation in a wide range of applications. Its small size, high level of stability and ease of integration make it an ideal solution for many modern electronic devices.
