quartz crystal
The quartz crystal, namely the silicon dioxide crystal, has the characteristics of piezoelectric properties. An electric potential field can be generated when the applied force is applied on the surface in a certain direction. On the contrary, when an electric field is applied on the surface, the mechanical deformation or vibration can be induced. The frequency of its vibration depends on:
A: size of quartz crystal wafer
B: the crystal slice is relative to the crystal axis of the tangential, also the cut type
C: ambient temperature
D: oscillating circuit load conditions
Pressure of piezoelectric quartz crystal is used after silicon electronic materials, used in the manufacture of selection and control of frequency of electronic components, widely used in the fields of electronic information industry, such as color TV, air conditioning, computer, DVD, no communication cables, etc., especially in high performance electronic devices and digital equipment application is expanding. Piezoelectric crystal products are the main varieties: Z rod, Y rod, film thickness, frequency IMG

Quartz crystal resonator
Quartz crystal resonator, commonly known as crystal. Is the resonant elements made by piezoelectric effect of quartz crystal. Together with a semiconductor device and a resistance capacitance element
The quartz crystal oscillator can be formed by using the crystal oscillator.
