Working Principle

The working principle of the 633V12502I2T oscillator is quite simple. It uses an analog-to-digital converter to convert a reference clock signal into a digital signal. This digital signal is then converted back into an analog signal using a digital-to-analog converter. The output of the digital-to-analog converter is then fed back to the analog-to-digital converter, creating a feedback loop which allows for the generation of a stable oscillating signal.

This oscillating signal is used to drive the peripheral devices in the system. The frequency and amplitude of the signal can be controlled by changing the gain of the feedback loop. The frequency of the signal can be changed by varying the feedback loop gain and the amplitude of the signal can be changed by varying the reference clock frequency.
