The working principle of the SIT3821AI-2B-33NX is based on a voltage-controlled oscillator (VCO). The oscillator circuit consists of two parts: an Digital Wave Integrator (DWI), and a voltage controlled oscillator (VCO). The DWI is responsible for generating the oscillations and its frequency is determined by a voltage signal applied to an electrode in the DWI. The input voltage controls the magnitude and shape of the generated waveform, while the frequency is determined by the capacitive elements of the DWI. The output of the DWI is then fed to the VCO where its frequency is further adjusted by applying a voltage signal to an electrode in the VCO. This allows for fine-tune adjustments of the oscillation frequency.

In summary, the SIT3821AI-2B-33NX programmable oscillator is an ideal solution for applications that demand precision and accuracy in oscillator signals. It features a superior level of accuracy and stability, with an average frequency drift of ± 2.5ppm for operating temperatures between -55 to +85°C. Additionally, the SIT3821AI-2B-33NX offers a variety of programming and adjustment options, such as frequency output, triangle and amplitude modulation, data synchronizing and signal scaling. The working principle of the device is based on a voltage-controlled oscillator (VCO) circuit, enabling a wide range of frequency adjustments. Overall, the SIT3821AI-2B-33NX programmable oscillator is a high performance, low power, and cost-effective solution for a wide range of applications.
