Introduction

Programmable Oscillators can be divided into two broad categories, namely Voltage Controlled Oscillators (VCOs) and User-Programmable Oscillators (POVs). This article will focus on the SIT8008BIU2-25N, a user-programmable oscillator. We will discuss its application field and working principle.

Application Field

The SIT8008BIU2-25N is a unique and versatile user-programmable oscillator that offers experienced embedded development engineers a combination of features not seen in a single product. It brings together a wide range of features to create an oscillator that can be adapted to many industrial control and embedded applications.Firstly, the wide temperature range (-20°C to +70°C) makes it suitable for operations in extreme environments. Secondly, it offers both Digital and Analog programming which makes it convenient for development engineers to use and configure. Thirdly, the 8-phase operation makes it epamile for operations in advanced applications such as power management, motor control and industrial automation. Last but not least, its high accuracy (1ppm) makes it ideal for precision measuring in harsh industrial settings.

Working Principle

The SIT8008BIU2-25N oscillator works on the principle of phase-locked loop (PLL). The PLL consists of two main components, the phase detector and the voltage-controlled oscillator (VCO). The phase detector compares the input signal with the output signal of the VCO. This comparison is then used to generate a control voltage which is then applied to the VCO to cause it to adjust its frequency. Thus, the frequency of the output signal of the VCO is dictated by the input signal and the PLL provides the feedback necessary to ensure that the output signal remains in sync with the input signal.The SIT8008BIU2-25N oscillator features both Digital and Analog programming and a user can choose from pre-defined frequency settings or set a custom frequency through one of the programming methods. The oscillator can be powered either using DC voltage or using a voltage source, as per user requirement.

Conclusion

This article has presented the application field and working principle of the SIT8008BIU2-25N user-programmable oscillator. It is designed to be used in rough industrial environments, and its wide temperature range, digital and analog programming, 8-phase operation and high accuracy make it a great choice for many industrial control and embedded applications. It works on the principle of PLL and it can be powered either using DC voltage or using voltage source.
