Description

• A crystal oscillator will create an electrical signal with a given frequency.
• This frequency is commonly used to keep track of time.
• Quartz crystal is mainly used in radio-frequency (RF) oscillators.
• Quartz crystal is the most common type of piezoelectric resonator, in oscillator circuits, we are using them so it became known as crystal oscillators.
• Crystal oscillators must be designed to provide a load capacitance.
• Usually, quartz crystal oscillators are highly stable, consist of good quality factor(Q), they are small in size, and are economically related.
• Hence, quartz crystal oscillator circuits are more superior compared to other resonators like LC circuits, tuning forks.
• Generally in Microprocessors and Micro controllers we are using an 8MHz crystal oscillator.
