It is mainly used for circuit integration, clock synchronization mainly for digital integrated circuit and microprocessor systems, providing an accurate the clock signal, and has been widely used in computers, communications, consumer electronics, automotive electronics and other fields.

Working Principle

The quartz crystal used as the resonating element of ABM11W-25.0000MHZ-4-J1Z-T3 is composed of electrodes, a quartz crystal blank and a holder. It has the characteristics of small volume, high frequency accuracy, low temperature drift, long-term stability and shock resistance. The quartz crystal control oscillator comprises an oscillator circuit composed of an operational amplifier and external capacitance, and the quartz crystal. The quartz crystal oscillator circuit is excited by an alternating current, and the quartz crystal is initially in a high-amplitude elastic vibration state. The quartz crystal has at least two resonance frequencies, the series resonance frequency (Fs) and the parallel resonance frequency (Fp), and the ABM11W-25.0000MHZ-4-J1Z-T3 frequency is 25MHz.The frequency of the oscillator is determined by the quartz crystal and other attributes, and the time interval between two positive or negative electricity is maintained unchanged.

In the electrical field, the quartz crystal can be equivalent to an oscillator which can improve the accuracy of the clock signal oscillation and make the circuit oscillate with a certain frequency. The specific working principle is: the quartz crystal is a piezoelectric material, and its internal crystal atoms will cut off the external electric field stress and generate a continuous small electric field current in the circuit. This electric current is amplified by an amplifier and then passed through the circuit. It will encounter a certain phase offset when phase becomes the initial reference phase; the phase offset and the electric field stress applied to the crystal by the exciting circuit will produce an internal voltage, which will further impact the quartz crystal, forming a closed loop. The closed-loop feedback amplifies the external field generated by the electric current, so that the quartz crystal can oscillate at a certain frequency.

Conclusion

ABM11W-25.0000MHZ-4-J1Z-T3 is a high precision quartz crystal resonator, mainly used in computer, communications, consumer electronics and automobile electronics, provides a accurate clock signal, and has a wide application range. Its working principle is that the external electric field stress is cut off by the internal crystal atoms, generating a small electric field current in the circuit, and the phase difference and electric field stress produced by the electric current feedback further impact the crystal, forming a closed loop, excessively amplifying the electric current and quantifying to oscillate at a certain frequency.
