A crystal oscillator is an electronic oscillator circuit made of Quartz Crystals that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. This frequency tracks time, as in quartz wristwatches. It provides a stable clock signal for digital integrated circuits and stabilizes frequencies for radio transmitters and receivers.

Features

• High-frequency Stability
• High Frequency of operation
• Can obtain High Precise and Stable frequency
• Frequency does not vary much with Temperature and another parameter change
• High Q factor

Application

• In the frequency synthesizers.
• Special types of receivers.
• In radio and TV transmitters.
• As a crystal clock in microprocessors.
