445A23F27M00000

Crystal oscillators are commonly used in a variety of electronic applications as a source of an accurate frequency signal.

A 445A23F27M00000 is a type of surface ambient crystal oscillator that can accurately regulate the frequency of a generated signal over the life of the oscillator. It uses a quartz crystal as the resonator element and is built using a Silicon on Insulator (SOI) structure, where a Silicon layer is implanted on an Insulator substrate. This SOI structure enhances the performance of the oscillator, making it more reliable and accurate than other types.

Application Field

The 445A23F27M00000 oscillator can be used in a wide variety of applications, including digital data communication, measurement and control systems, timing circuitry, data networks, and more. It is especially useful for applications that require precise frequency control, such as in ultra-low power designs, which require less power consumption than traditional crystal oscillators. This oscillator is also suitable for use in high-temperature environments, such as in Industrial, Automotive, and Automation applications.

Working Principle

The key component of a crystal oscillator is a quartz crystal. The crystal is cut in a specific shape and is usually held between two electrodes. When an alternating voltage is applied to the crystal, it vibrates at its Resonant frequency, creating an oscillating electric signal. The oscillating signal is then amplified by an amplifier stage and used to generate a frequency which is locked to the resonant frequency of the crystal.

The 445A23F27M00000 oscillator also has an additional feature to enhance its frequency stability. It contains a mechanical feedback system, where the crystal is attached to a beam that is connected to a moving mass. When the crystal vibrates, the beam slightly moves and this mechanical motion adjusts the frequency of the oscillator.

The oscillator also includes additional components such as capacitors and resistors, which are used to further adjust the operating frequency. Finally, the output signal is conditioned by the output stage and delivered to the application.
