Oscillators are devices designed to generate periodic signals, typically with a stable specified frequency. They are used in many applications and fields, from communications to sound production. The SIT9120AI-2C1-25E133.333300T is an example of an oscillator, specifically designed for the purpose of maintaining a steady frequency across varying temperature and power supply levels. This article will explore the application fields in which this oscillator operates, as well as the working principles behind it.

Application Fields

The SIT9120AI-2C1-25E133.333300T oscillator is designed primarily for use in timing and RF applications, with the precision frequency control and stability over varying temperatures providing an ideal tool for many applications. For example, the device is commonly found in television receivers and integrated circuits, where precise frequency control is essential for accurate audio/video production. The device is also capable of producing high frequency signals up to 75 MHz and is often employed in RF circuits as a control oscillator. Additionally, its accuracy makes it suitable for a wide range of frequency measurement and test instrumentation.

Working Principle

The SIT9120AI-2C1-25E133.333300T oscillator works on the principle of “clock synchronization”. That is, the device synchronizes the frequency at which it operates to a predetermined clock frequency, which is set as a parameter in the circuit. The device is equipped with a temperature-controlled oscillator (TCO), which serves as the basis of the synchronization mechanism. The TCO utilizes a thermistor, whose resistance value changes with the temperature, to control the oscillation frequency of the circuit. The varying resistance of the thermistor corresponds to different temperatures and thus keeps the frequency of the oscillator steady throughout any fluctuations in ambient temperatures.

In addition to the TCO, the SIT9120AI-2C1-25E133.333300T oscillator also contains a power supply control circuit. This circuit is designed to ensure that the voltage at the output does not exceed a predetermined level by controlling the steady voltage applied to the oscillator’s internal components. This steady output voltage enables the device to maintain higher frequency accuracy while regulating the power supply levels.

Conclusion

The SIT9120AI-2C1-25E133.333300T oscillator is a precision timing device designed to provide an accurate and reliable frequency control across a wide range of temperature and power supply variations. With its temperature-controlled oscillator and efficient power supply control circuit, the oscillator is suited for a variety of applications in timing and RF fields, such as television receivers and integrated circuits. Through the integration of these two components, the oscillator is able to maintain steady frequency regardless of changes in temperature and power supply levels.
