Crystals: The ABM11W-38.8800MHZ-8-D1X-T3 Application Field and Working Principle

Crystals are an essential part of all electronic devices. Like the motherboard of a computer, the frequency oscillator of a phone, and even the transmitter of a satellite, all rely on crystals to generate and transmit signals or provide a high-quality timing basis. In this article, we will analyze the ABM11W-38.8800MHZ-8-D1X-T3 crystal – a product of American manufacturer Abracon – and discuss its application field and working principle.

Application Field & Applications

The ABM11W-38.8800MHZ-8-D1X-T3 crystal is a surface-mount quartz crystal oscillator (SMD-type crystal) with a frequency of 38.8800 MHz, a tolerance of 8 ppm, and a temperature stability of ±3 ppm. It can be used in a broad range of applications, including:

• Wireless LAN
• Bluetooth
• WiMAX
• GPS systems
• Modems and router
• Data communications equipment
• Medical/telemetry equipment
• Automotive electronics
• Magnetic Resonance Imaging (MRI) equipment

Due to its excellent temperature stability, the ABM11W-38.8800MHZ-8-D1X-T3 is also suitable for the most demanding of applications, so it can be used in any field where a precise timing is required.

Working Principle

The basic principle of operation of a quartz crystal is the piezoelectric effect. This effect, discovered in 1880 by Pierre Curie and Jacques Curie, states that when a quartz crystal is placed in an electric field it produces mechanical vibrations called harmonics. These vibrations can then be used to generate electrical signals of exactly the same frequency.In the case of the ABM11W-38.8800MHZ-8-D1X-T3 crystal, these harmonics are used to generate a precisely 38.8800 MHz signal. The crystal is composed of two layers of quartz, each coated with electrodes. When a voltage is applied to the electrodes, the quartz layers expand and contract, creating an oscillating electric field. This in turn creates mechanical energy at a stable frequency of 38.8800 MHz.The oscillation is maintained even when the voltage is removed, due to the restoring force of the quartz layers’ inertia. This property of quartz crystals is known as “free running”, and it allows the crystals to maintain their precision frequency even when not connected to a power source.

Conclusion

In conclusion, the ABM11W-38.8800MHZ-8-D1X-T3 crystall is an versatile device with broadly applicable uses. The piezoelectric effect allows the crystal to generate an oscillating electric field of precisely 38.8800 MHz, while the free-running properties of the quartz layers ensure that this frequency can be maintained even when the crystal is not connected to a power source.
