Crystals play a very important part in various electrical engineering applications. The CX3225GB18432P0HPQCC crystal is a very versatile type that has been used in many different products. This article will discuss the application field and working principle of the CX3225GB18432P0HPQCC crystal.

The CX3225GB18432P0HPQCC crystal is a small, 4 pin, through-hole package crystal with a frequency range from 18.432 MHz to 8.000 MHz. This type of crystal has been used in a wide range of applications including communications, computing, automotive, and industrial equipment. In communications systems, the crystal can be used for modulating and demodulating digital signals, frequency selection, and providing clock signals for various components. In computer systems, it can provide various timing functions such as serial communications and memory refresh timing. In automotive applications, the crystal can be used as an onboard transceiver, while its widely-applicable frequency range makes it ideal for a broad range of industrial applications.

This type of crystal consists of a quartz crystal bonded between two metal plates. The quartz crystal has the attribute of piezoelectricity, which means it responds to an applied electric field. When an alternating electric field is applied, the quartz crystal vibrates in an harmonic frequency known as the fundamental frequency. The crystal is surrounded by an electrical circuit to convert the electric field into a voltage. The applied voltage causes the crystal to vibrate with a frequency double that of the fundamental frequency. This doubled frequency is called the overtone.

The frequency obtained from a crystal is dependent on its shape, size and the dielectric used to coat the crystal. The CX3225GB18432P0HPQCC crystal is made of quartz and the dielectric used is titanium dioxide (TiO2). The crystal is cut and polished to produce an optimal resonator that vibrates at a frequency within the specified range when energised. The two metal plates are then bonded to the quartz crystal and these metal plates form the electrical circuit necessary to convert the electric field into a voltage.

When a current is applied to the electrical circuit, the applied voltage causes the quartz crystal to vibrate. The harmonic frequency of this vibration is determined by the size and shape of the crystal and is within the required range. The frequency of the vibration can then be measured to determine the exact frequency of the crystal and the circuit is adjusted accordingly. This process is known as trimming and once the frequency has been set, the crystal oscillator is ready for use.

In conclusion, the CX3225GB18432P0HPQCC is a very versatile type of crystal that has been used in many different applications. Its frequency range is ideal for a wide range of applications and its small, 4 pin, through-hole package makes it a convenient component to use in tight spaces. Its construction consists of a quartz crystal coated with a dielectric material such as titanium dioxide and metal plates that form the electrical circuit required to convert the electric field into a voltage. When a current is passed through the circuit, the crystal vibrates at its specified frequency which can then be measured and adjusted accordingly. This process is known as trimming and it is an essential part of the manufacturing process for this type of crystal.
