Working Principles

The working principle of quartz crystal is based on the piezoelectric effect. Piezoelectricity is the physical phenomenon where an electric charge is created when an applied mechanical stress changes the shape or volume of a material. Quartz crystal is a type of material that exhibits this effect, and when an alternating voltage is applied to it, the quartz crystal will move back and forth, creating oscillations.

The 402F300XXCDT series of quartz crystals use the principle of the oscillator to generate accurate and precise timing signals. These oscillator devices consist of three elements – an electronic amplifier, a frequency determining element, and a feedback element. The frequency determining element is the quartz crystal. When a voltage is applied to the quartz crystal, it starts to vibrate at its resonant frequency, and the amplifier amplifies the vibrations and sends them to the feedback element. The feedback element then transmits the signal back to the amplifier, forming a loop that generates a repeating oscillating signal.

The quality of the generated signal depends on both the crystal and the amplifier. The 402F300XXCDT series of crystals offer excellent frequency stability due to their high quality quartz material. As for the amplifier, the 402F300XXCDT series use the most advanced technology to ensure a low power consumption and a high signal to noise ratio.

In addition to offering accurate and precise timing signals, the 402F300XXCDT series of crystals also offer features like short start-up times and low operating current. These features enable the crystals to be used in a variety of applications, from consumer electronics to industrial and medical equipment.

Conclusion

The 402F300XXCDT series of crystals offer excellent frequency stability, short start-up times and low operating current, making them suitable for a wide range of applications. These crystals use the oscillator principle to generate accurate and precise timing signals, with the performance of the signals being determined by the quality of the quartz crystal and the amplifier. These crystals are mainly used in consumer electronics, automotive infotainment, industrial and medical equipment and other applications.
