Crystal Oscillator In Microcontroller. The equivalent electrical circuit also represents the crystal action of the crystal. Other options include external canned oscillators resonators rc oscillators and internal clocks.

Generally 8mhz crystal oscillator is used in microprocessors and microcontrollers. The optimum clock source type for a particular application is dependent on factors including cost accuracy and environmental parameters. The crystal oscillators or ceramic resonators are connected with the pins osci and osc2 in lp xt or hs modes for establishing the oscillating.
Crystal oscillators are handy devices that consist of a quartz crystal and the additional circuitry needed to generate a standard digital clock signal.
Thus it uses mechanical resonance of a vibrating crystal of piezoelectric materiel to create an electric signal with very precise frequency. The optimum clock source type for a particular application is dependent on factors including cost accuracy and environmental parameters. A crystal oscillator is an electronic oscillator circuit which uses inverse piezoelectric effect ie when electric field is applied across certain materials it produces mechanical deformation. The equivalent electrical circuit also represents the crystal action of the crystal.
