Working Principle

The working principle of the ABLS2-12.288MHZ-D4Y-T crystal is relatively simple. The principle of operation of a crystal is based on the piezoelectric effect. Piezoelectric crystals are made of a special material, such as quartz, that exhibits a characteristic of producing electric charge when it is subjected to mechanical stress or strain. In the same way, when a voltage is applied across the crystal, it responds in a mechanical manner and vibrates at a certain frequency. The ABLS2-12.288MHZ-D4Y-T crystal is cut in such a way that it produces a vibration frequency of exactly 12.288MHz when the frequency of the applied voltage matches certain parameters.

The ABLS2-12.288MHZ-D4Y-T crystal can be driven with alternating current (AC) voltage or direct current (DC) voltage with a frequency close to the resonant frequency. A series resistor and a capacitor are usually connected in parallel to the crystal, forming a resonant circuit called an oscillator. The DC voltage applied to this circuit causes the crystal lattice to vibrate at its resonant frequency. This oscillating voltage can then be used as an input signal to an electronic IC or circuit. Additionally, the external resonant circuit of the oscillator can be adjusted to adjust the output frequency or phase of the vibrating voltage at the terminals.

The ABLS2-12.288MHZ-D4Y-T crystal is a type of quartz crystal that offers excellent frequency stability and accuracy over a wide frequency range. This makes it suitable for many commercial applications, including frequency control, signal transmission, and many other electronic control applications. Crystals such as the ABLS2-12.288MHZ-D4Y-T are essential components in many electronic devices and systems.
