Working Principle

The SIT8208AC-G2-18S-66.666660X Oscillator operates on a basic oscillator circuit. It consists of a voltage-controlled oscillator (VCO) and a voltage-controlled amplifier (VCA). The VCO generates the oscillating signal and the VCA amplifies the signal to an appropriate level. The frequency of the oscillations is determined by the capacitance between the VCO and VCA nodes. This capacitance can be adjusted by varying the applied voltage, thereby allowing the oscillator to generate different frequencies.

The SIT8208AC-G2-18S-66.666660X Oscillator also incorporates a temperature-compensated voltage-controlled crystal oscillator (TCVCXO) for greater frequency stability over temperature. The TCVCXO uses a quartz crystal to generate a stable frequency, and temperature compensation circuitry to ensure the frequency remains stable even when the temperature changes.

The output of the SIT8208AC-G2-18S-66.666660X Oscillator is stable, low-jitter, and suitable for use in high-speed, high-performance applications.
