Working Principle

The SIT9005ACU1G-30DG is a programmable oscillator that relies on Digital Phase Lock Loop (DPLL) technology to generate an accurate and stable output signal. The oscillator comprises an input stage, a PLL stage and an output stage.

The input stage consists of a high-performance voltage-controlled oscillator (VCO) and a programmable frequency synthesizer. This stage is responsible for generating the reference frequency and providing a control voltage to the PLL stage.

The PLL stage consists of two main components: a phase detector and a charge pump. The phase detector compares the input frequency to the reference frequency and generates a control voltage to the charge pump. The charge pump adjusts the voltage level of the VCO so that it is in phase with the reference frequency.

The output stage consists of a low-noise amplifier and a filter. The amplifier is responsible for amplifying the signal to the desired level, and the filter is used to reduce the noise and ensure that the signal has the desired frequency and shape.

Overall, the SIT9005ACU1G-30DG is a reliable and accurate programmable oscillator that is ideal for a wide range of applications. Its wide frequency range, high resolution and excellent temperature range make it an excellent choice for many systems.
