Crystals are widely used in many technological applications, such as quartz clocks, radio receivers, and satellite communication. Among them, the 8Z-27.120MAAJ-T oscillator is an important type of crystal which is widely used to generate certain frequency signals or to control the frequency of an oscillator. This article will discuss the 8Z-27.120MAAJ-T application field and working principle.

Application Field

The 8Z-27.120MAAJ-T oscillator mainly consists of a quartz crystal and circuitry associated with it. This crystal is primarily used for high frequency, low jitter clock generation which is the most important application for the 8Z-27.120MAAJ-T oscillator. It is also used for synthesizing complex voltage control oscillators, such as those used in communication receivers and transmitters, because of its superior jitter and frequency stability. The 8Z-27.120MAAJ-T oscillator is also popular in microprocessor based systems because it can generate an accurate reference frequency as required by the application.

Working Principle

The 8Z-27.120MAAJ-T oscillator is based on the principle of piezoelectricity. Piezoelectricity is the electric charge generated in certain materials due to the application of mechanical stress. Quartz crystals display the property of piezoelectricity when they are subjected to mechanical stress. When an external electric field acts on the crystal, the electrons get displaced from their original positions and form an electric dipole. When the stress is removed, the electrons return to their original positions, resulting in the release of electric energy.

In a quartz crystal oscillator, the quartz crystal is connected to an external circuit using two electrodes or terminals. An external electric signal, usually in the form of a sine wave, is applied to one of the electrodes. This signal is called the "excitation signal". The excitation signal causes the quartz crystal to vibrate an electric dipole with the same frequency as the external signal. This vibration of the quartz crystal creates an oscillating voltage which is then amplified by the external circuit, creating the oscillator output signal.

The 8Z-27.120MAAJ-T oscillator relies on the same principle as other quartz crystal oscillators, with the main difference being that it uses a special type of quartz crystal with enhanced frequency and temperature stability. This makes it ideal for applications that require highly accurate frequency signals such as timing and communications.

Conclusion

The 8Z-27.120MAAJ-T oscillator is a type of quartz crystal oscillator which is used in many applications due to its high frequency stability and low jitter. It is based on the principle of piezoelectricity, whereby an external electric signal is used to cause the quartz crystal to vibrate an electric dipole. The oscillator output is then amplified by the external circuit, creating the oscillator output signal. The 8Z-27.120MAAJ-T oscillator is widely used for high frequency, low jitter clock generation, as well as synthesizing complex voltage control oscillators.
