In this article, we will discuss the application field and working principle of SIT9003AC-8-33SO, one of the most popular programmable oscillators in the market.

Application Field

The SIT9003AC-8-33SO oscillator is designed for a wide variety of applications, including drones, telecom, test & measurement, printing, medical and other industrial applications. It is designed for high accuracy, low phase jitter, low power and high EMI/RFI immunity. It is also suitable for power sensitive applications that require minimal power consumption.

The SIT9003AC-8-33SO oscillator has an electrical specification range of 0 to 3.3V, and a frequency range of 8kHz to 33MHz. It is also suitable for multiple voltage levels, and can accommodate a variety of temperature range requirements. In addition, the package size is very small, which makes it ideal for applications that require a small footprint.

Working Principle

The SIT9003AC-8-33SO oscillator is based on metal-oxide-semiconductor (MOS) technology. It consists of a metal-oxide-field-effect transistor (MOSFET) and a resistor. The metal-oxide-field-effect transistor is a three-terminal device with a gate, drain and source. The resistor is used to control the current flow through the device. The MOSFET is arranged in an RC-oscillator configuration.

The working principle of the MOSFET is based on the phenomenon that when a voltage is applied to the gate of the MOSFET, the drain-source current starts to increase exponentially. This phenomenon is known as the “pinch-off” effect. When the voltage is removed, the current decreases exponentially.

In the RC-oscillator configuration, the frequency of the oscillator is determined by the time constant of the resistor-capacitor (RC) circuit. The time constant is determined by the value of the resistor and the capacitance of the capacitor. When the frequency of the oscillator is matched to the desired frequency, the oscillator will be in continuous oscillation.

The SIT9003AC-8-33SO oscillator also has a built-in temperature compensation circuit. This circuit is designed to reduce output frequency variation due to temperature changes. It is designed to ensure that the frequency of the oscillator remains within a specified frequency tolerance over a wide range of temperatures.

Conclusion

In conclusion, the SIT9003AC-8-33SO programmable oscillator is an ideal solution for applications that require high accuracy, low phase jitter, and low power consumption. It is based on metal-oxide-semiconductor technology and comes with a built-in temperature compensation circuit. This oscillator is suitable for a wide range of applications, including drones, telecom, test & measurement, printing, medical and other industrial applications.
