Crystals are ubiquitous in modern life, with applications ranging from everyday technology to specialized laboratory equipment. One such example of a crystal is the FA-238 25.0000MA30X-C3. This quartz oscillator module is a versatile and dependable solution for various frequency control applications.The FA-238 oscillator module is designed for use in Frequency-Division Multiplexing (FDM) equipment, as well as Frequency-Division Duplexing (FDD) and Frequency-Division Multiple Access (FDMA) systems. This crystal is ideal for communication links, clocks, timers, automated detection and measurement applications, as well as other uses which require precise timing and synchronization.The FA-238 crystal is a miniature ceramic oscillator with a quartz crystal that offers a wide operating temperature range. The ceramic package offers a highly resistant environment and makes the device highly reliable. The quartz crystal is temperature compensated and provides a stable frequency with minimized aging effects over a wide temperature range. The device also has a low ESR (Equivalent Series Resistance) and promises low power dissipation.The FA-238 also has very good frequency stability with temperature and is able to provide exceptionally accurate timekeeping. The FA-238 is also vibration-resistant and delivers low current operation while at the same time maintaining a high level of accuracy. The device is capable of providing a wide frequency range from 25.0000MHz to 30.0000MHz.The fundamental working principle at the core of the FA-238 is the same as that of any quartz crystal: the mechanical property of piezoelectricity. Piezoelectricity, which literally translates as electricity from pressure, is the process whereby mechanical stress is converted into electrical energy. Quartz is one of several substances that exhibit this property. In the case of this oscillator, a quartz crystal is subjected to mechanical stress under a DC electric field. This stress causes the crystal to vibrate at its resonant frequency, and an electrical signal is generated that is proportional to this frequency. This signal is then used as the timekeeping reference for the oscillator.In summary, the FA-238 25.0000MA30X-C3 is a ceramic oscillator module with a quartz crystal. It is designed for Frequency-Division Multiplexing (FDM), Frequency-Division Duplexing (FDD), and Frequency-Division Multiple Access (FDMA) systems, and can typically be used in communication links, clocks, timers, automated detection and measurement applications, as well as other uses which require precise timing and synchronization. It has a wide operating temperature range, low power dissipation, and is vibration-resistant. Its fundamental working principle takes advantage of the piezoelectric effect in quartz, which converts the mechanical stress of an electrical field into an electrical signal that is proportional to the quartz’s resonant frequency.
