Crystal Oscillator. In most vxo circuits the output frequency starts slightly above the marked frequency of the crystal cl at minimum capacitance and moves lower as the cl capacitance is in creased. Using a crystal oscillator circuit enables a high performance high stability oscillator to be built very cheaply and easily.
But the transistor pierce crystal oscillator is the most commonly used one. Consumer applications of crystal oscillator crystal oscillators are used in many consumer goods such as cable television systems personal computers video cameras toys and video games radio systems cellular phones and so on. Crystal oscillators are used in many areas of electronics.
In most vxo circuits the output frequency starts slightly above the marked frequency of the crystal cl at minimum capacitance and moves lower as the cl capacitance is in creased.
