Oscillators are widely used in the fields of electronics engineering requiring constant frequency operation, such as radio waves, computer technology, and communication technology. This article will provide an overview about oscillators, the application field and working principle of ECX-H27CM-148.500.

What are Oscillators?

Oscillators are widely used in modern inductive electronics technology, such as radio wave and other communication signal transmiters. It produces repetitive electrical or acoustic signal by alternately switching state when coupled circuit parameters reach to certain level.

There are three most commonly used oscillators in the fields of electronics engineering, which are the crystal oscillators, the RC oscillators and the LC oscillators.

The Crystal Oscillator

The most common type of oscillator is the crystal oscillator. It is formed by coupling an electrical circuit formed by the integrating crystal quartz oscillator and its driving circuits. It has very good temperature stability, and can provide an accurate and stable in frequency and its frequency change is very small with the influence of the temperature. Crystal oscillators can widely be applied to radio waves, computers and communication technology field.

The RC oscillator

RC oscillators are formed with the combination of resistors and capacitors, which can be in either a series circuit or a parallel circuit. It has substantially lower temperature stability and precision than crystal oscillators, but it features a dynamic operation range, low cost and is easier to be integrated with ICs.

The LC oscillator

LC oscillators are formed with the combination of inductors and capacitors, which can also be in either a series circuit or a parallel circuit. Compared to RC oscillators, it features about twice higher power and is more stable but less dynamic in oscillation. Without the high integration with ICs, it has long been replaced by other more efficient oscillators.

The Application Field and Working Principle of ECX-H27CM-148.500

The ECX-H27CM-148.500 utilizes a series circuit resonant circuit formed by the quartz crystal resonator and the integrated driving circuit, which completes the high-precision frequency setting and temperature stability. Along with excellent performance and stability, It also has wide-range stability for amplitude.

In addition, due to its low power consumption, small volumn and excellent stability, the ECX-H27CM-148.500 is also applicable for applications such as DTS, WBTS and other temporal frequency modulation techniques. Compared to other types of oscillators, the ECX-H27CM-148.500 crystal oscillator features superior stability and low power consumption, making it essential for radio communications, telecommunication transmissions, and other modern electronics.

In terms of operation, the basic working principle of crystal oscillator is to resonate with the quartz crystal resonator. The quartz crystal within the oscillator creates periodic vibrations when exposed to the charge from the drive circuit. The voltage signal is amplified by the drive circuit in different cycles and feed back to the quartz crystal resonator. This oscillation process continues until the circuit parameters reaches a certain level and is stoped when overloaded.

Overall, the ECX-H27CM-148.500 crystal oscillator is very applicable for various electronic communication fields. Its small volumn, low energy consumption, excellent stability and performance leads it to be an ideal choice for modern electronic gadgets.
