Oscillators: SIT1602AI-82-33E-74.250000Y

Oscillators are widely used for a variety of applications requiring an accurate output signal of a particular frequency. This article will discuss the application field and working principle of the SIT1602AI-82-33E-74.250000Y oscillator, which is a crystal oscillator manufactured by Sitronix as part of their AI Series.

Application Field

The AI Series oscillator is designed for use in a wide range of applications requiring precision timing signals. These include:

• Servo motor systems
• Television, computer, audio, and video equipment
• Communication systems
• Data buses
• Transmitters
• Automotive systems

The oscillator is also suitable for use in other systems that require the output frequency to remain within a set tolerance.

Working Principle

The SIT1602AI-82-33E-74.250000Y oscillator operates using the piezoelectric effect. This phenomenon occurs when a material, in this case quartz, is subjected to mechanical stress which changes the shape of the material and causes a charge separation in the material. This charge separation creates an electrical field which causes a voltage to be generated across the material.When the voltage reaches its peak value, the material begins to relax and the voltage decreases. As the voltage decreases, the electrical field decreases, causing the material to vibrate at the same frequency as the voltage. This creates a mechanical wave which, when combined with the electrical field, creates an oscillating output signal.

Conclusion

The SIT1602AI-82-33E-74.250000Y oscillator is a high-precision timing device used in a variety of applications requiring precise timing signals. It relies on the piezoelectric effect to create an oscillating signal which can be accurately and reliably produced. This makes it a useful device for applications that require precise timing.
