Crystals are a wide variety of elements, ranging from diamonds to quartz, and their particular uses have remained essential to a wide range of industries over the years. The FA-238 21.2000MB-C is one example of a specific crystal that has been developed over the years, and its application field and working principle is explored in this article.

Crystals aren\'t just pretty and highly sought after gems. They can actually be used in any device that requires precise or high frequency timing. Such as quartz oscillators, flicker free peripheral circuits, and many other electronic components. The FA-238 21.2000MB-C crystal is an integrated oscillator that can generate frequencies over a wide range ranging from 100 kHz to 185 MHz. Its applications are numerous and some of the main ones include: L-band satellite navigation, GSM/UMTS base station clock, WiMAX base station clock, and ZigBee home automation networks.

The FA-238 21.2000MB-C crystal is composed of a quartz resonator and a miniature amplifier that is sealed together in a vacuum-sealed package, making it waterproof and very reliable in many applications. The quartz resonator provides the clock signal, while the miniature amplifier provides the drive voltage necessary to achieve the desired frequency. The frequency can be adjusted within certain limits by varying the drive voltage. The quartz resonator also serves an important role in the temperature stability of the oscillator, making it suitable for temperature-sensitive applications.

The working principle of the FA-238 21.2000MB-C crystal is based on the quartz resonator, which is a dielectric material that is capable of producing an electric field when placed in an alternating current. The electric field acts as a waveguide and the wave propagates along the quartz material. As the frequency of the waveguide increases or decreases, so does the phase shift of the wave fronts that propagate along the quartz, which can be used as a timing reference for oscillators.

The crystal oscillator uses the quartz resonator in order to generate an accurate, repetitive signal, that is used as a reference for many operating systems, such as computers and communication devices. This signal is then used to accurately measure time and to synchronize the data transmitted between devices. The quartz resonator also helps reduce power consumption and improves stability in communication devices.

In conclusion, the FA-238 21.2000MB-C crystal is a reliable and precise quartz oscillator that can generate frequencies ranging from 100 kHz to 185 MHz for many applications. Its working principle is based on the quartz resonator and the miniature amplifier, and its reliability comes from the vacuum-sealed package, and its temperature stability. Its applications are numerous, ranging from L-band satellite navigation, GSM/UMTS base station clock, WiMAX base station clock, and ZigBee home automation networks. In addition, it helps reduce power consumption, and improve stability in communication devices.
