3 , product application
Development of quartz crystal oscillators and their applications in wireless systems.
4 , product features
Industrial grade crystal commonly known as: wide temperature high temperature crystal, crystal and so on, is that in industrial grade crystal, at least the working temperature than the civilian level of -20 - 70 degrees wide, its working temperature is -40 and 85 C, chip cutting type is BT, these two points is very critical.
5 , product advantage
The highest accuracy of TCXO crystal can reach 0.1ppm.
