It is also suitable for frequency coordination in a wide range of communication systems.

The working principle of the SIT8208AC-3F-18S-66.666600X crystal oscillator is simple. An oscillator consists of a device (often a crystal) that is capable of generating a periodic signal. A voltage is applied to the crystal, which causes it to vibrate at its natural frequency and produce a periodic signal. This signal is then amplified and shaped, and its phase is locked to the voltage that was initially applied.

The crystal oscillator is coupled with a phase-locked loop. The phase-locked loop is a feedback circuit which controls the amplitude of the oscillator’s output signal. The phase-locked loop detects any changes in frequency or phase, and adjusts its output to compensate and keep the output signal at its desired frequency.

The combination of the crystal oscillator and the phase-locked-loop allows the SIT8208AC-3F-18S-66.666600X crystal oscillator to provide a reliable and stable frequency source for a wide range of applications. It is an accurate and inexpensive source of time and frequency reference for communication and control systems.
