Crystals: FA-238 48.0000MB-B Application Field And Working Principle

Crystals represent a form of electromagnetic radiation with a relatively short wave length and high frequency. They are usually divided into two primary categories: piezocrystals and optical frequency crystals. The FA-238 48.0000MB-B is a type of piezocrystal, also known as a thin-film vibrator, manufactured by Frequency Application Corporation. The crystal belongs to the family of quartz crystals and is used in a variety of applications due to its various attributes.

Application Fields

FA-238 48.0000MB-B crystals are typically used to generate precise frequencies within electronic devices and are often used as clock sources in digital systems. Due to their precise timing attributes and small form factor, they are used in a variety of products, including radios, GPS receivers, television and video games, scientific instruments, and medical devices. The crystal is also used in frequency-sensitive application such as modulation, demodulation, or filters.

The crystal is capable of providing stable and precise frequencies with excellent phase-noise characteristics. This makes it especially suitable for use in high-end consumer, professional audio, and industrial applications where clock accuracy is necessary. Further, its low operating voltages and low current consumption make it an attractive choice for energy-sensitive applications.

Working Principle

FA-238 48.0000MB-B crystals are manufactured by sputtering a thin film of quartz on the surface of an electrode. When the crystal is energized by a signal near its resonance frequency, the quartz vibrates and functions as a resonator. The frequency at which the crystal vibrates is determined by its geometry and is fixed at a specific frequency when manufactured. The crystal can then be used to oscillate or tune any electronic device.

When the crystal is energized, the voltage across the crystal causes it to oscillate at its resonance frequency. The oscillations cause an alternating electrical field, which is characterized by an oscillation frequency referred to as its resonance frequency. The resonance frequency of the crystal is determined by its physical geometry, and these are pre-defined when the crystal is manufactured.

The oscillations of the quartz crystal cause an alternating current, referred to as the "crystal current". The crystal current is typically in the milliamp range and is used to oscillate or control the frequency of an electronic circuit or device. The amplitude of the crystal current is determined by the quality factor Q of the crystal. By controlling the amplitude of the crystal current the oscillating frequency of the circuit or device can be precisely controlled.

Conclusion

FA-238 48.0000MB-B is a type of piezocrystal known as a thin-film vibrator manufactured by Frequency Application Corporation. It is used to generate precise frequencies within electronic devices, typically as clock sources in digital systems. The crystal emits a crystal current that is characterized by an oscillation frequency referred to as its resonance frequency, and is also used to oscillate or tune any electronic device. Its precise timing, energy-sensitive attributes, and small form factor make it an ideal choice for high-end consumer, professional audio, and industrial applications.
