Crystals: CM309E20000000CHLT Application Field and Working Principle

Crystals are an essential part of electronic circuit design. The CM309E20000000CHLT crystal is a type of crystal that is commonly used in many applications due to its various features and functionalities. In this article, we will explain the application field and working principle of the CM309E20000000CHLT crystal.

Application Field

The CM309E20000000CHLT crystal is mainly used for oscillating signals in RF circuits. It is often found in wireless communication devices, such as wireless LANs, radios, and global satellite systems. It can also be used in other applications such as digital watch crystals, VLF receivers, and frequency control devices.

Working Principle

The CM309E20000000CHLT crystal works by resonating at a particular frequency. It is a quartz crystal that is surrounded by two metal plates which act as electrodes. The quartz crystal is cut in such a way that it has two opposite faces that are parallel but are slightly angled. When electric energy is applied to the crystal, the two faces resonate at a certain frequency which is determined by the physical dimensions of the quartz crystal and the type of electrode used. This frequency can be accurately determined and kept within a narrow range by manufacturing the crystal with tolerance. The crystal is placed in an oscillator circuit and the oscillator output is then fed to an amplifier or a radio frequency (RF) circuit. The output from the amplifier or RF is then sent to the device being controlled or monitored. The oscillator output depends on the frequency of the quartz crystal and the input signals.

Conclusion

The CM309E20000000CHLT is a common type of crystal used in many applications. It resonates at a particular frequency when electric current is applied and is used in oscillator circuits for controlling or monitoring devices. Its accuracy is ensured by its physical dimensions and the type of electrodes that surround the quartz crystal. The CM309E20000000CHLT crystal is an essential part of modern electronics and is used in a wide range of applications.
