Working Principle

A crystal oscillator is an electronic device consisting of a vibrating crystal of AT-cut quartz and an amplifier connected to it. The oscillator works by driving a quartz crystal at its preferred frequency (usually between 10 kHz and 50 MHz). The quartz crystal is a piezoelectric element that is mechanically and electrically asymmetric. The crystal vibrates in response to an applied electrical signal, producing an oscillating current at the desired frequency. This oscillating current is then fed back to the input of the amplifier, resulting in an oscillating signal at the crystal\'s resonant frequency.

In addition to providing an oscillating signal at the desired frequency, the crystal oscillator also helps to ensure that the frequency remains stable over time. This is because the quartz crystal is a very stable material and its resonant frequency is relatively unaffected by temperature, pressure and other environmental factors.

Advantages

The main advantage of using a crystal oscillator over other types of oscillators is its superior stability. The crystal can be extremely accurately tuned to a given frequency and is capable of maintaining its frequency with a very high degree of accuracy over long periods of time, even when exposed to wide variations in temperature, pressure, and other environmental factors. Additionally, because the crystal vibration is confined within a special package, it is relatively immune to noise and other interference from the environment.

The 445A25L20M00000 crystal oscillator is also quite rugged and can withstand quite harsh conditions without being damaged. This makes it suitable for use in a variety of extreme environments, such as high-vibration environments or those with high shock or pressure fluctuations.
