Oscillators

Oscillators are electronic circuits which produce a continuous periodic electrical signals. SIT1602BI-72-28N-33.000000G is a type of oscillator, specifically designed for high performance oscillator and frequency control applications. Here is an overview of its application field and working principle.

Application Field

SIT1602BI-72-28N-33.000000G is designed to meet the needs of high-performance oscillator and frequency control, especially those of demanding systems, for instance digital radios, communication systems, process control systems and personal computing. The combination of excellent performance and low power consumption make this type of oscillator ideal for these applications. Additionally, its intrinsic features such as wide frequency range, high accuracy, low jitter, adjustable temperature range, low phase noise, minimal power consumption and robust design enable it to be used in diverse applications enviroments.

Work Principle

SIT1602BI-72-28N-33.000000G is based on a design using LC circuits, as this circuit type allows for excellent performance in terms of power consumption and frequency stability. An oscillator is made up of two parts: a voltage controlled oscillator (VCO) and a comparator with feedback, which in combination with a resistor-capacitor (RC) network, form the oscillator circuit. The oscillator starts at the VCO with a frequency set by a frequency control voltage (Vcont). This produces an output signal with a frequency that depends on the value of Vcont. The signal is fed into a comparator which compares the signal to another signal from the RC network in order to detect the frequency error. The comparator then produces a feedback voltage, which is sent back to the VCO to adjust its frequency. This adjustment maintains a constant feedback voltage and keeps the oscillator locked into the frequency determined by the Vcont setting. It is this constant feedback voltage which provides the oscillator with the required accuracy and stability.

Conclusion

To conclude, SIT1602BI-72-28N-33.000000G oscillator offers a reliable, accurate and low power solution for applications requiring a high performance oscillator and frequency control. Its adjustable temperature range, wide frequency range and low jitter make it a uniquely adaptable solution to various application requirements. Its principle of operation, namely a VCO and comparator circuit combined with a RC network, is simple yet robust and reliable. In essence, this type of oscillator provides the necessary accuracy and sensitivity for modern electronic systems.
