Crystal Oscillator Circuit is an electronic circuit used to generate stable frequency. Its main function is to provide an accurate and stable clock signal.

The crystal oscillator circuit uses a British crystal called a crystal resonator (Crystal Resonator). A crystal resonator has a resonant frequency, and by exciting the crystal resonator in a circuit, it will start to oscillate at its natural resonant frequency. This oscillation frequency is very stable and can provide an accurate clock signal.

Crystal oscillator circuit usually consists of crystal resonator, amplifier and feedback circuit. The oscillation frequency of a crystal resonator depends on the physical properties and size of the crystal, so it can provide a very precise and stable frequency. The amplifier amplifies the weak oscillation signal generated by the crystal resonator to a practical usable level and sends it back to the crystal resonator to form a closed-loop feedback. This feedback process will keep the oscillation frequency stable and provide an accurate clock signal.

Crystal oscillator circuits are widely used in many electronic devices and systems, such as computers, communication equipment, radios, displays, etc. They provide accurate and stable clock signals to ensure the normal operation of equipment and systems, and ensure the accuracy and reliability of various functions such as data transmission, timing, and synchronization.
