Oscillators: AOCJY2A-26.000MHZ-E-SW Application Field and Working Principle

Oscillators are electrical circuits capable of producing repetitive signals, usually in the form of electrical sine waves. Oscillators are widely used in electronic industries for numerous applications, including communications, computing, sensing, control, measurement and automotive systems. The AOCJY2A-26.000MHZ-E-SW oscillator is a highly reliable voltage-controlled crystal oscillator (VCXO) used in a wide variety of frequencies and signal categories. This article explores the application fields and working principles of the AOCJY2A-26.000MHZ-E-SW oscillator.

Application

The AOCJY2A-26.000MHZ-E-SW oscillator is designed mainly to be used in clock applications and to provide a stable, synchronized signal over a wide range of temperatures and conditions. It supports a variety of signal types, such as square wave, sine wave, saw tooth and triangle wave, making it a universal option for different circuits and applications. As an ultra-miniature VCXO, it is suitable to be placed on small circuit board designs within limited space.It can be used as an on-board clock generator for flicker synchronous video signal control in video system applications. It is also suitable as a reference clock source in audio applications including sampling rate converters, digital mixers and audio processors. Similarly, it is used for frequency control of microwave networks and for RF upconverters, downconverters and frequency synthesizers in wireless communication systems. Moreover, it is used as an external clock source in other oscillator circuits, such as pulse generated circuits.

Working Principle

The operating principle of the AOCJY2A-26.000MHZ-E-SW oscillator is analogous to that of a conventional oscillator circuit. It consists of a quartz crystal, a bias capacitor, a resistor and a MOS transistor. The quartz crystal is composed of two quartz slabs, each of which accommodates two electrical plates. The two plates at the top and the bottom make up the two oscillating plates with an air gap of a few tens of micrometers between them. The MOS transistor acts as an amplifier to amplify the signal compressing the quartz crystal. The amplifier boosts the amplified output from the MOS transistor, as well as providing feedback to the capacitor, which works as a stabilizer, suppressing any sudden variations in the oscillations. As the voltage applied to the crystal increases, the frequency of the oscillations also increases. This phenomenon is known as voltage control; hence the name of the oscillator.

Conclusion

The AOCJY2A-26.000MHZ-E-SW is a reliable, highly accurate voltage-controlled crystal oscillator designed for multiple applications. It is suitable for frequency control in RF circuits, digital mixers, video signal control, microwave networks and other oscillator circuits, and is also available as an ultra-miniature form factor for use on limited space circuit board designs. The oscillator operates on the principle of compressing quartz crystal plates between two plates within a few tens of micrometers of air gap, and it is stabilized by amplifier and bias capacitor feedback. With the diverse applications and reliable working principle, the AOCJY2A-26.000MHZ-E-SW oscillator is an ideal choice for many applications.
