Working Principle of the SIT9002AI-48N25DO

The SIT9002AI-48N25DO is a programmable oscillator based on a hybrid design that allows the user to generate a wide range of frequencies with a single oscillator. It consists of a Ceramic DRPG oscillator core, a Digital Note Generator, and a Digital PLL.

The Ceramic DRPG Oscillator Core provides a fundamental frequency of 25 MHz with a frequency range of 5 Hz to 200 MHz. It then uses a digital PLL to adjust and scale the oscillation frequency to up to 2.6 GHz. The Digital Note Generator (DNG) is then used to set the exact frequency of the oscillator.

The oscillator can be programmed by downloading the desired frequency settings into the DNG, which then generates a digital pattern that is used to program the core oscillator. The digital PLL then adjusts the oscillator frequency to the desired value. The SIT9002AI-48N25DO also has a low power consumption and a low harmonic distortion ratio.
