Oscillators

Oscillators are widely used in many applications, such as in radio broadcasting, telecommunication, and control systems. The SIT1602BI-12-18S-40.000000G is one example of such an oscillator. This article will discuss the application field and working principle of this oscillator.

Application Field

The SIT1602BI-12-18S-40.000000G oscillator is used in both digital and analog applications, and in both commercial and industrial settings. It is primarily used in applications that need a high level of accuracy and reliability, such as frequency synthesizers, clock generators, delay lines, and time bases. It is also used in GPS receivers, security systems, medical devices, and High Altitude Platform (HAP) radars.

Working Principle

At its core, the SIT1602BI-12-18S-40.000000G oscillator is a type of voltage-controlled oscillator (VCO) that utilizes capacitance technology. It consists of a silicon chip, which is coated with conductive polysilicon. This chip is then divided into two distinct capacitors. One of these capacitors acts as a feedback loop, creating a frequency dependent on applied voltage, while the other capacitor acts as a coarse tuning element. This allows for precise voltage tuning and control of the frequency.

The device also features an oscillator buffer that amplifies signals to different levels. This ensures that signals maintain their form and minimize disturbances and noise. It also features two enable inputs (EN A and EN B) that can be used to control the output levels.

The device is operated by applying a voltage through an external potentiometer, driving the capacitors with different gain stages. The gain stages are balanced in such a way as to help maintain a steady output voltage and frequency while the external potentiometer is being adjusted. The frequency range of the device is 10kHz to 20GHz, making it suitable for a wide range of applications.

Conclusion

The SIT1602BI-12-18S-40.000000G oscillator is a versatile and reliable device used in a variety of applications. Its high level of accuracy, narrow frequency range, and adjustable gain stages make it a viable solution for various commercial and industrial applications. The device is also relatively easy to use and configure, and thus can be utilized in either analog or digital systems.
