What is Crystal Oscillator ?Crystal Oscillator DefinitionA crystal oscillator is defined as a device that uses the inverse piezoelectric effect to convert vibrations into stable oscillations.Working PrincipleThe oscillator works by applying an alternating voltage to a crystal, causing it to vibrate at its natural frequency.Circuit DesignCrystal oscillators are designed to operate in series-resonant mode (low impedance) or parallel-resonant mode (high impedance).Frequency StabilityThey offer exce
