Working Principle

The SIT9002AC-33H25SD is a programmable oscillator that operates by using a feedback loop. The frequency of the output is related to the capacitive feedback from the inductor and resistor. The frequency is adjusted through external control and the output frequency is controlled to within 1% of the set frequency.

The oscillator consists of three primary components: an amplifier, an inductor, and a capacitor. The amplifier Gain-Bandwidth product sets the frequency of the oscillator by controlling the phase shift in the capacitor. The capacitor and inductor form an LC oscillator circuit, which then sets the overall frequency of the oscillator.

The oscillator also has a power supply, which reduces the ripple noise, and a crystal that reduces the jitter. The crystal ensures that the oscillator will operate at the expected frequency even when it is operated at the extremes of temperatures, supply voltages, or environmental conditions.
