Crystal oscillators are widely used in electronic devices to provide precise timing signals for controlling the frequency and phase of electronic oscillators. The 7B-27.000MAAJ-T is a quartz crystal oscillator that is used in a wide variety of applications, from consumer electronics to aerospace and medical equipment. This article will discuss the application fields and working principle of this particular crystal oscillator.

Application Fields

The 7B-27.000MAAJ-T crystal oscillator has a wide range of applications. It is used in consumer electronics, such as mobile phones, digital cameras, and portable media players. It is also used in aerospace, automotive, and industrial applications, including military and medical equipment. Other applications include timing circuits, network communication systems, and frequency synthesisers.

Working Principle

The 7B-27.000MAAJ-T crystal oscillator is a quartz crystal oscillator that works by using the principle of changed electrical load. In this type of oscillator, the quartz crystal is energized by an external alternating current (AC) or direct current (DC) source, and its resonant frequency is determined by the crystal’s physical structure and the external environment. As current alternates, the crystal’s electrical field changes and stimulates waves on one end of the crystal. These waves then travel along the crystal and interact with the other side. The frequency of the waves is determined by the ratio the external load and the size, shape and composition of the quartz crystal.

The 7B-27.000MAAJ-T crystal oscillator has a frequency stability of 10 parts per million (ppm). This frequency is maintained regardless of temperature, humidity and other environmental factors that may affect crystal oscillators. The resonator design of this type of oscillator also provides superior jitter performance for better signal conversion, accuracy and reliability.

Conclusion

The 7B-27.000MAAJ-T crystal oscillator is a quartz crystal oscillator that finds application in a wide variety of fields, from consumer electronics to aerospace and medical equipment. It operates on the principle of changed electrical load, and provides superior jitter performance and frequency stability of 10ppm. This makes it a reliable and precise timing solution for many different types of applications.
