Crystals: CX3225SB12000H0PSTC1 Application Field and Working Principle

Crystals, such as the CX3225SB12000H0PSTC1, are key components in electronics and communication systems, as they provide an accurate time standard for operation and communication. The CX3225SB12000H0PSTC1 is a 3225 package surface mount quartz crystal with a frequency of 12MHz and 100ppm stability, and generally operates at 20 degrees Celsius.

The key applications for the CX3225SB12000H0PSTC1 are clocks, watches, cellular phones, computers, electronic measurement equipment, and electronic toys. The crystal will provide a stable frequency, allowing the system to run with precision timing.

Working Principle

All crystals work by using the piezoelectric effect. A quartz crystal will expand and contract when a voltage is applied to its surface. This process creates an oscillation when the crystal vibrates along its crystalline structure. The CX3225SB12000H0PSTC1 uses this oscillation to generate a precise frequency which can be used as a time reference for a circuit.

The CX3225SB12000H0PSTC1 consists of two metal plates, either gold or nickel-plated, and a quartz crystal. An oscillator circuit is connected between the two plates, and applies the alternating current or voltage to the crystal, which causes it to oscillate. The frequency of this oscillation can be controlled by adjusting the size of the crystal and the value of the load capacitors.

One of the key features of the CX3225SB12000H0PSTC1 is its frequency stability. It has a temperature stability of ±100 ppm over a range of -20°C to +70°C. This ensures a very accurate and consistent frequency output from the crystal, even in changing environmental conditions.

The CX3225SB12000H0PSTC1 quartz crystal also comes with a hermetic sealing, making it ideal for use in harsh environmental conditions, as it will protect the crystal from moisture, dust and other corrosive elements. It also provides electrical isolation between the quartz and other components in the same device.

Conclusion

The CX3225SB12000H0PSTC1 crystal is an essential component in a variety of electronic products and devices. It features a frequency of 12MHz and a temperature stability of ±100ppm, making it suitable for use in clocks, watches, computers, electronic measurement equipment and electronic toys. By utilizing the piezoelectric effect, the CX3225SB12000H0PSTC1 can oscillate at a precise frequency, ensuring accurate and stable time reference.
