The CX3225GB20000D0HPQCC is one of the most commonly used crystals for frequency control and related applications. In this article, we will discuss the application field and working principle of the CX3225GB20000D0HPQCC.

Overview

The CX3225GB20000D0HPQCC is a crystal from the Murata family of crystals. It has a center frequency of 20MHz with a stability of ±0.5ppm maximum over the operating temperature range. The crystal has a type F package and is suitable for reflow soldering up to 250°C. The package dimensions are 8.0 x 8.0 x 2.5 mm.

Application Field

The CX3225GB20000D0HPQCC has a wide range of applications due to its center frequency, accuracy and stability. It is an ideal choice for the use in RF applications, particularly frequency-dependent communication systems. It is also used in touch screen controllers, frequency synthesis, generation and sweeping circuits, as well as frequency-related medical applications.

Working Principle

The working principle behind the CX3225GB20000D0HPQCC is based on the piezoelectric effect. This effect states that certain materials will produce an electric potential when a mechanical strain is applied to them. The material used in this crystal is quartz and when it is cut and polished, it will react to mechanical stress by producing an electrical signal. The CX3225GB20000D0HPQCC is carefully cut to a specific size, which determines its resonant frequency. Two metal electrodes are attached to the quartz crystal, which allows the passing of electric current.

When a voltage is applied to the two electrodes, an oscillation will be induced in the quartz crystal. This oscillation will be in the form of an electrical sine wave and it will be at the pre-set frequency of 20MHz. This oscillation can be used as a frequency reference or can be fed into an amplifier to increase its signal strength.

Conclusion

The CX3225GB20000D0HPQCC is a common crystal from the Murata family. It has a center frequency of 20MHz and a stability of ±0.5ppm maximum. The main application fields of the crystal are the RF applications, frequency synthesis, generation and sweeping circuits, as well as frequency-related medical applications. The working principle of the crystal is based on the piezoelectric effect, and it is able to generate a sine wave of a preset frequency by applying a voltage to the electrodes.
