Crystals: ECS-36-20-1X-EM Application Field and Working Principle

Crystals are the basic building blocks of the modern world we live in today. They are highly versatile devices used for a variety of applications, ranging from the very mundane to the most complex. One such crystal is the ECS-36-20-1X-EM, a piezoelectric dual frequency micro electromechanical system (MEMS) crystal. This device is useful in a variety of applications, and its working principle is vital to understand.

Applications

Crystal oscillators, such as the ECS-36-20-1X-EM, are used for a wide range of timing and communication applications. The most prominent application is in the telecommunications field, where it is used as a mobile phone base station synchronized clock. It is also used in digital television broadcasting, satellite navigation, and avionics.

In addition, crystal oscillators are also used in consumer electronics such as microwaves and washing machines, as well as computer system boards, including microprocessor motherboards. It is also used in devices such as automatic teller machines (ATMs), video game consoles, and industrial equipment.

Working Principle

The working principle of a crystal oscillator involves the generation of an electrical output signal at a specific frequency. This frequency is determined by the physical properties of the crystal, such as its shape, size, and orientation. The crystal is composed of two electrodes, one connected to the crystal and the other connected to a source of a constant electrical potential. When a voltage is applied to the crystal, a mechanical force is produced due to the piezoelectric effect, causing the crystal to vibrate.

The vibration of the crystal creates an electrical current that oscillates at a specific frequency determined by the crystal\'s properties. This frequency is called the resonance frequency of the crystal, and is determined by the physical characteristics of the crystal, such as its size and orientation. The electrical output signal is then filtered and processed through a voltage controlled oscillator (VCO) to form the desired output signal.

Conclusion

The ECS-36-20-1X-EM crystal oscillator is a versatile and reliable device used in a wide range of applications. It is easy to use and has an output signal that is precise, stable, and reliable. Understanding the working principle of a crystal oscillator is essential for those looking to use this device in their applications.
