Working Principle

The SIT8209AC-G3-33E-166.666666T oscillator is a quartz crystal-based oscillator that utilizes frequency pulling, where the frequency of the oscillator is adjusted by controlling a variable resistor in the circuit. It has two oscillations modes—open loop and closed loop; with open loop being identical to a standard oscillator and closed loop allowing for more precise adjustments. In open loop, the oscillator is driven by a voltage step that causes the crystal frequency to oscillate between a maximum and minimum frequency determined by a selected resistor value. In closed loop, this voltage step is adjusted in real time to maintain a specific frequency.

In addition, the input and output buffer provides a noise reduction. The buffer helps reduce distortion caused by impedance mismatches, and it ensures that the output signal has a consistent frequency. Furthermore, the SIT8209AC-G3-33E-166.666666T offers excellent thermal stability, allowing it to maintain frequency accuracy over a wide temperature range.
