The SIT9002AI-38N33DX is a programmable oscillator that is widely used in many industries. This oscillator is an integrated complex clock source, with programmable output sources, designed to provide high performance and flexibility in different types of applications.

Programmable oscillators are commonly used in computer and networking applications, where they are used to generate clock signals for digital logic and communication purposes. Specifically, the SIT9002AI-38N33DX is designed for applications that require low jitter and high accuracy, such as telecom, 5G, automatic driving, military, smart city, and industrial IoT applications.

The SIT9002AI-38N33DX uses a Phase Locked Loop (PLL) architecture that allows it to generate an output frequency that can be programmed to any frequency within its specified frequency range. The integrated programmable output sources of this oscillator support a wide range of outputs, including LVPECL, LVDS, CMOS, HCSL, and any combination thereof. This allows for maximum flexibility for applications with different output requirements.

The SIT9002AI-38N33DX features high performance and accuracy, with low jitter performance of 550fsec at a 1MHz input. The device also features low power consumption of 75mW at a nominal voltage of 1.8V. It has a small package size of 5mm x 4mm, allowing for improved system design and easier integration.

The working principle of the SIT9002AI-38N33DX is quite unique. The device’s integrated digital frequency synthesizer (DFS) enables the user to control the output frequency and jitter performance, as well as to store multiple output frequency settings to suit different application requirements. The DFS is also able to provide a precise output frequency over a wide frequency range, with a hassle-free tuning process.

The internal clock multiplier, which is a PLL circuit, is used to generate the desired frequency output. The PLL takes an input reference frequency and multiplies it by an integer “N” to construct the desired output frequency. The integer “N” is programmed using the DFS and stored in the on-chip memory as the output frequency setting. The output frequency is then stabilized using low-jitter phase detectors.

The device also features an on-chip temperature compensated voltage controlled oscillator (TCVCO), which is used to maintain phase jitter performance over temperature. This oscillator is able to automatically adjust its frequency and phase jitter performance in response to changes in temperature, allowing for improved system stability.

Overall, the SIT9002AI-38N33DX is an excellent choice for applications that require both high performance and flexibility. Its integrated components provide a comprehensive solution for applications such as telecom, 5G, automatic driving, military, smart city, and industrial IoT applications. The device’s PLL-based architecture and on-chip DFS add to its impressive performance and accuracy, making it a perfect choice for many applications.
