For example, in the mobile communication system, the crystal oscillator controls the transmission and reception frequency of the signal, ensuring the normal communication of the mobile phone; it is used in microcomputer system to determine the instruction cycle, ensure the accuracy of the system operation, and it can also be used in wireless products to determine the communication frequency, thus ensuring the normal transmission of the data.

2. Working Principle

The ABM8W-24.5455MHZ-4-J2Z-T3 crystal is a type of quartz crystal, and its frequency controlling device consists of a quartz crystal tube, two external capacitors, a power amplifier (including an inverter) and a parallel acceleration circuit.In the crystal oscillator driving circuit, when a small current flows through the quartz crystal tube, the quartz oscillator vibrates with its own mechanical resonance frequency. When the frequency of the vibration reaches the resonant frequency of the quartz oscillator, it can generate a relatively strong simple harmonic signal. The frequency stability of the signal depends on the thickness, temperature, shape and quality of the quartz crystal.The external capacitor can provide a frequency-tunable load to balance the quartz oscillator system, so as to ensure the stability of the frequency and output power of the quartz oscillator. When the frequency of the oscillator needs to be adjusted, changing the capacitance of the external capacitor can adjust the frequency and maintain stable oscillation and high precision; while the power amplifier circuit can amplify the oscillation signal of the quartz oscillator and make it meet the general power requirement of the system.

3. Summary

In short, the ABM8W-24.5455MHZ-4-J2Z-T3 crystal is a widely-used frequency control component with a wide range of applications, and its working principle is that the small current flows through the quartz crystal tube and generates a simple harmonic signal with stable frequency and high precision, which is regulated by the external capacitor and power amplifier circuit.
