Introduction

Oscillators are widely used in electronic systems for their ability to keep repeating a signal in the form of an oscillation or waveform. Among them, SIT1602BC-71-30N-72.000000G is a new type of oscillator, which has been developed in recent years. In this article, we will introduce the application field and working principle of SIT1602BC-71-30N-72.000000G in detail.

Application Field

SIT1602BC-71-30N-72.000000G oscillator is mainly used in low-frequency applications (10KHz to 200KHz). It is commonly used in digital signal processors, data control circuits, signal generators, digital filters, analog receive transmitters, digital signal amplifiers, decoding systems, and other applications in communication systems or instrumentation systems. Besides, it also provides impressive power saving under light loads, while being stable and reliable. In particular, it is suitable for design oriented to low power, ensuring the robustness and reliability of the system.

Working Principle

As a type of oscillator, SIT1602BC-71-30N-72.000000G is driven by the collector-base junction of a transistor, with the collector voltage and the base current controlling the frequency of oscillation. The device operates in its linear region with a frequency controllable in a wide range. In order to achieve good temperature stabilization, an additional current is also provided via the collector-emitter junction. This current can be adjusted by an external voltage, and its task is to control the collector current variation due to environmental changes. Moreover, SIT1602BC-71-30N-72.000000G includes an automatic bias circuit to maintain the collector current under certain parameter operating conditions, and to keep the transistor operating in the linear region. As a result, the frequency drift produced by environmental factors and aging effects can be effectively compensated for.

Conclusion

In summary, the SIT1602BC-71-30N-72.000000G oscillator mainly operates in its linear region, with external control of the collector voltage and base current controlling the frequency. Its collector-emitter junction also carries an additional current that can be adjusted externally. The type of oscillator offers excellent power saving capability, high frequency stability and a wide frequency range under different environmental conditions. Together, these features make this oscillator a great choice for low-frequency applications.
