Working Principle

The SIT8208AI-2F-18S-4.000000T functions as an oscillator by utilizing a temperature compensated reference oscillator (TCXO). The TCXO consists of a quartz oscillator that is connected to an amplifier circuit and a temperature compensating circuit. The temperature compensating circuit adjusts the oscillator frequency so that it remains stable over a wide range of temperatures. The TCXO is then connected to a programmable frequency divider. The output of the frequency divider is then connected to the input of a voltage-controlled oscillator (VCO).

The VCO is used to generate an output frequency based on the input signal from the frequency divider. This output signal is then fed into a phase-locked loop circuit. The phase-locked loop (PLL) is used to compare the input signal with the generated output signal. If the input signal changes, the PLL adjusts the frequency of the VCO to match the input signal. The PLL is also able to maintain a stable output frequency even if there is a slight variation in the input signal.
