So what is the application field and working principle of ATS204SM-1E crystal?

Application Field of ATS204SM-1E Crystal

ATS204SM-1E crystal with nominal frequency of 20MHz and frequency tolerance of ±20ppm is mainly used in the fields of short, ultra short and long distance communication, local area network, and satellite communication. It is especially suitable for medium and high frequency applications.

ATS204SM-1E crystal can withstand wide range of temperature from -40°C to +85°C. In addition, the crystal is made of hard quartz with good durability and anti-vibration ability. Its maximum power rating is 0.8W, the equivalent series resistance can be as low as 200Ω and the insulator resistance is greater than 1GΩ. It’s an ideal choice for low power, high frequency and temperature-resistant applications.

Working Principle of ATS204SM-1E Crystal

The ATS204SM-1E crystal is a high-quality quartz crystal, which is designed by making use of the piezoelectric effect of quartz crystals. Quartz crystals have the ability to generate electricity when subjected to pressure. And when voltage is applied to the crystal, it will vibrate at a fixed frequency. Hence, ATS204SM-1E crystal can generate a periodic signal when it’s powered. By connecting the circuit to the crystal, oscillating electric signals can be generated to ensure the accuracy of frequency.

Basically, the ATS204SM-1E crystal system consists of a quartz crystal, a drive oscillator and an amplifier. When voltage is applied to the crystal, an electric current will be generated and runs through two electrodes. The two electrodes will cause the distort of the crystal structure and make the quartz crystal oscillate at a fixed frequency. The circuit of the drive oscillator will amplify the electric signal generated by the oscillate crystal. Finally, the amplified electric signals driving the output unit will generate the oscillation output.

Conclusion

The ATS204SM-1E crystal has wide application in communication, computers and precision instruments. With the wide working temperature range, low power rating, low equivalent series resistance and high durability, the ATS204SM-1E crystal is an ideal choice to ensure the accuracy and high level of performance. Moreover, ATS204SM-1E crystal works by making use of the piezoelectric effect of quartz crystals and driven by an oscillator and amplifier circuit. All these characteristics make the ATS204SM-1E crystal a great option in the fields of communication, computers and precision instruments.
