Crystals: application field and working principle

Crystals are among the most common but yet important fields of electronics. They are usually used in various instruments and consumer electronic devices, such as microwaves, TVs, radios, phones and even watches. Crystals are the tiny quartz quartzine oscillators which, when energized by a voltage frequency, produce highly accurate frequency signals for synchronization purposes. Crystals can be broadly divided into two main types: active and passive.

Active Crystals

Active Crystals typically have an integrated circuit (IC) within the crystal structure. They are usually used for more complex operations, such as generating complex and reliabel frequency signals over longer periods of time. They tend to be moreexpensive than passive crystals due to their additional components and complexity. Nevertheless, they offer a greater level of accuracy, stability and consistency.

Passive Crystals

In contrast to their active counterparts, Passive Crystals contain no electronics, and rely on their form, shape and size to create a precise frequency. Their frequencies are usually tailored to a specific task. Due to their simplicity and low cost, they are widely used in consumer electronics, such as mobile phones, wrist watches and alarm clocks.

Furthermore, it is specially made for clocks and precise frequency generation, and provides an excellent solution for a variety of high frequency applications.

Application Field

Typical application fields where the ABM8W-38.4000MHZ-8-B1U-T3 crystal may be applied include communication systems, medical devices and electronic instruments. This crystal is used in communication systems to accurately synchronize data by providing a highly reliable and consistent frequency output. Similarly, medical devices employed in collecting and analyzing bodily tissues, as well as electronic instruments used in measuring and testing, also use the crystal to ensure reliable frequency signals in order to accurately calculate their results.

Working Principle

When the crystal is energized by an external voltage from a power supply, the piezoelectric quartz resonator inside the crystal begins to oscillate at a predefined frequency. This oscillation produces an alternating current (AC) of the same frequency on the crystal - that is, the ABM8W-38.4000MHZ-8-B1U-T3 crystal oscillates at 38.4000MHZ. This AC voltage is then supplied to the device it is integrated into, and used as a reliable frequency source.

Conclusion

The ABM8W-38.4000MHZ-8-B1U-T3 quartz crystal is widely used in various electronic applications due to its low-cost and simple operation. The crystal is a passive one, integrated with no electronics, and requires an external power supply to generate an AC frequency output of 38.4000MHZ. Its reliable frequency signals make it highly useful in medical and communication systems, electronic instruments and other consumer electronics, like TVs, audio-systems and watches.
