Working principle of ECS-35-17-4XDN

The crystal oscillator of ECS-35-17-4XDN works on the principle of piezoelectricity. The quartz crystal generates equal and opposite voltage signals when the electric field is applied to it. A quartz crystal consists of three parts - a quartz resonator, a ceramic base, and two pins connecting the ceramic base and the resonator.The quartz resonator consists of at least two metal electrodes placed on the opposite side of the quartz structure. When electric field is applied to it, it generates a small electric charge. The charge produces an opposite electric field which is applied on the quartz and generates an electric voltage. At the same time, electric signals due to vibration will be transmitted to the quartz resonator thus the electric field alternates.The alternating frequency of the quartz crystal is determined by the resonant frequency of the quartz resonator and the frequency of the quartz crystal is generally very stable. The ECS-35-17-4XDN is an excellent quartz crystal with both high frequency stability and low temperature coefficient.

Conclusion

The ECS-35-17-4XDN is an excellent crystal with many application fields, especially for high frequency and low frequency communication systems, mobilecommunication system, wireless local area network, time-relevant wireless equipment, and so on. Its working principle is based on the piezoelectric effect generated by the quartz resonator. The frequency of the quartz crystal is generally very stable, and the ECS-35-17-4XDN has the excellent performance in terms of high frequency stability and low temperature coefficient.
