Crystals can be found in myriad forms and serve a wide range of applications, from the simple and classic timekeeping of wristwatches, to the complex guidance systems of missiles. One such crystal is the ABM8W-38.4000MHZ-4-B2U-T3, a quartz crystal component in the 8-pad MHz series of crystals from the manufacturer AVX Corporation. In this article we will examine the application field and operating principles of this specific component.

Application Field

The ABM8W-38.4000MHZ-4-B2U-T3 crystal component is a reliable source of stable frequency and accurate timing. It is designed to operate as an oscillator in a quartz-based crystal oscillator to generate precise frequencies and thus reliable signal timing in many electronic applications. These applications may include radio transmitters and receivers, telecommunications networks, cellular networks, and timing devices, such as timers, alarm clocks, and chronographs.

The component is also particularly suitable for precise frequency generation in computer systems, for example for the precise clock signal for a microprocessor. It is also used in the synchronization of hand-held devices, such as smartphones, to allow the precise exchanging of audio and video signals, as well as providing precise timing in audio and video studio technology, or in hi-fi systems.

Working Principle

Quartz crystals are essentially a piezoelectric material that vibrates when a voltage is applied to it. This vibration is then passed on to the quartz crystal component every time a small current is applied. As the quartz crystal component is essentially a mechanical resonator operated in an electronic circuit, the frequency of oscillation is dependent on its shape, size, and the tension of the quartz crystal.

The ABM8W-38.4000MHZ-4-B2U-T3 crystal component is specifically designed to have an operating frequency of 38.4000MHz, which is accurately maintained by the optimized tension of the quartz crystal material. When the component is used in a quartz-based crystal oscillator, it is connected to an oscillator circuit that also contains an amplifier, a feedback capacitor and an inductor. The component will then provide a precisely frequency-controlled signal to the amplifier, which is subsequently connected to the oscillator circuit.

Once the oscillator circuit is set up, the crystal component will begin to oscillate at a frequency of 38.4000MHz and will generate a precise clock signal with minimal frequency variations. This clock signal can then be used by electronic systems as a timing device.

Conclusion

The ABM8W-38.4000MHZ-4-B2U-T3 crystal component is a reliable piece of quartz crystal technology, designed for frequency and timing stability in a wide range of electronic applications. It is optimized to generate an accurate clock signal at the frequency of 38.4000MHz, and is a vital component for systems that need precise frequency and timing stability.
