Introduction

Oscillators are integral parts of many electronic systems and devices, as they provide a stable reference frequency. The most common of these are crystals, however, there are other oscillator types such as SIT9120AI-2C3-25S106.250000Y. This is a dual-source frequency stabilized oscillator, typically used in switching power supplies for their excellent temperature and time characteristics. In this article, we will address the application field and working principle of the SIT9120AI-2C3-25S106.250000Y oscillator.

Application Fields

The SIT9120AI-2C3-25S106.250000Y oscillator has a wide range of applications thanks to its low phase voltage, low jitter and outstanding frequency stability over voltage, time and temperature. It can be used in many applications, such as:• Switching mode power supplies• Renewable energy converters• Motor drive systems• Test and measurement equipment• Radar systems• Satellite communications• Medical equipment

Working Principle

The SIT9120AI-2C3-25S106.250000Y oscillator is a frequency stabilized oscillator that utilizes two independent sources of control. First, the oscillator is controlled by a quartz crystal resonator, which provides the reference frequency for the oscillator. Second, the oscillator is controlled by a temperature compensated reference voltage source (TCVRSS), which helps to maintain frequency accuracy over temperature, voltage and time.The oscillator also incorporates a trimming circuit, which is used to adjust the frequency output over temperature (TTC) and over time. The SIT9120AI-2C3-25S106.250000Y is designed to provide a very low phase voltage and assured temperature stability.

Conclusion

The SIT9120AI-2C3-25S106.250000Y oscillator is a dual-source frequency stabilized oscillator, used in many applications such as switching mode power supplies, renewable energy converters and motor drive systems. It utilizes a quartz crystal resonator and a temperature compensated reference voltage source (TCVRSS) to provide excellent low phase voltage, low jitter and outstanding frequency stability over voltage, time and temperature. The oscillator also has a trimming circuit, which allows for adjustment of the frequency output over time and temperature.
