Crystal Oscillator The cryatals are either naturally occuring or synthetically manufuctured, exhibiting the piezoelectric effect means under the influence of the mechanical pressure, the voltage gets generated across the opposite faces of the crystal Crystal If the mechanical force is applied in such a way to force the crystal to vibrate, the a.c voltage get generated across it. Conversely, if the crystal is subjected to a.c voltage, it vibrates causing mechanical distortion in the crystal shape. Every crystal has its own resonating frequency depending on its cut. So under the influence of the mechanical vibrations, the crystal generates an electrical signal of very constant frequency. The crystal has a greater stability in holding the constant frequency A crystal oscillator is basically a tuned-circuit oscillator using a piezoelectric crystal as its resonant tank circuit. The crystal oscillator are preferred when grea...
