Crystals are one of the most important components in electronic circuits. CM309E12288000ABET is a type of crystal and it has a wide range of applications in different fields. In this article, we will discuss the application field and working principle of this crystal.

What is CM309E12288000ABET?

CM309E12288000ABET is a type of crystal oscillator that operates at a frequency of 12.288MHz and has a two-point mounting style. This type of crystal is made of three quartz plates which ensures a stable frequency output without any significant variation. The quartz plates are embedded in a ceramic package and then wire bonded to the circuit.

Application Field

CM309E12288000ABET is widely used in different electronic circuits and systems. It is often found in various communication equipment like base stations, satellite tracking systems, and mobile phones. This oscillator is also used in some industrial and medical applications, such as high-frequency welding, X-ray imaging, laser cutting, and ultrasound scanning. Besides, it is also used in some precision timing devices, such as clocks and quartz watches.

Working Principle

CM309E12288000ABET works according to the piezoelectric principle. This concept is based on the fact that when mechanical stress is applied to quartz crystal, it produces an electric charge. When an alternating electric field is applied to the quartz crystal, it will vibrate at a certain frequency, thus producing an oscillating voltage at its electrodes.

In CM309E12288000ABET crystal, the quartz plates mentioned above reflect most of a passing alternating field due to their piezoelectric property. This reflected energy will be combined with the energy of the original alternating field, thus producing a resonance and producing an oscillating voltage at the electrodes. The frequency at which this voltage is produced is determined by the size and shape of the quartz plates.

Advantages

CM309E12288000ABET crystal is characterized by several advantages such as high stability, low power consumption, and low cost. The quartz plates used in this device are extremely stable and will not change significantly over time. Moreover, the power consumption is very low as the device vibrates at frequency without any significant input from the external electric field.

Additionally, CM309E12288000ABET crystal is highly cost-effective as it can be reused multiple times and can be configured to different frequencies by changing the plates’ size and shape. Moreover, the device is relatively smaller in size and thus can easily be placed in tight spaces.

Disadvantages

The main disadvantages of this device are that it has limited frequency range and low frequency accuracy. Also, the mechanical stress applied to the quartz plates will quickly break them down over time. This can be avoided by proper handling and maintenance.

Conclusion

CM309E12288000ABET crystal is a type of crystal oscillator with a wide range of applications in different fields. It works according to the piezoelectric principle and offers several advantages such as high stability, low power consumption, and low cost. However, it has some drawbacks such as limited frequency range and accuracy. Thus, careful handling and proper maintenance should be done to ensure the longevity of this device.
