Working Principles

SIT9002AC-48N25ST uses a quartz crystal to generate a stable frequency. The quartz crystal acts as a resonator, with mechanical properties that generate an electrical oscillation at a specific frequency when a voltage is applied across it. The frequency of the oscillation can be adjusted slightly by adding a series of capacitors or inductors in parallel to the quartz crystal.

The oscillator can be programmed by adding a series of capacitors or inductors in parallel to the quartz crystal. The capacitors or inductors act as a filter, allowing only the desired frequency to pass through. By controlling the resistance and capacitance values of these components, the frequency of the output signal can be adjusted. The serial interface provides access to program the capacitor/inductor values, as well as to select the output frequency.

SIT9002AC-48N25ST is relatively low-cost and reliable compared to other programmable oscillators. It requires minimal external components, reducing design cost, component count and component size. Furthermore, it can be programmed easily and quickly, making it ideal for applications where the frequency needs to be changed frequently.
