Working principle

The working principle of ABM8W-28.2240MHZ-8-B1U-T3 crystals is based on the piezoelectric effect. The quartz crystal within the package is cut in a specific orientation, and when an electric field is applied to it, the crystal vibrates at its resonance frequency. This frequency is determined by the thickness and shape of the quartz crystal. These crystals are manufactured to tight tolerances, resulting in reliable frequency stability.

In order to generate a continuous vibration, a feedback amplifier is used to maintain a steady oscillating current. This is connected to the crystal and the oscillator circuit, and ensures that the resonance frequency remains constant. The crystal is also connected to a frequency divider circuit in order to generate higher or lower output frequencies as needed.

The ABM8W-28.2240MHZ-8-B1U-T3 crystal is designed to work in both fundamental and overtone modes. In fundamental mode, the crystal vibrates at its primary frequency (known as the fundamental frequency). In overtone mode, the crystal vibrates at a higher frequency (known as the overtone frequency), which is an integer multiple of the fundamental frequency. This allows the crystal to be used in higher frequency applications, while still maintaining accuracy.

The ABM8W-28.2240MHZ-8-B1U-T3 crystal is a small, low-power device which provides high accuracy in frequency-critical applications. Its small size and low power consumption makes it ideal for use in portable or mobile devices, and its wide temperature range allows for reliable performance in most environments. Its piezoelectric properties allow for precise and repeatable generation of high-frequency signals, allowing it to be used in oscillator, timing, and frequency-critical applications.
