Operating Principle

The SIT9120TC-2C2-33S133.330000T oscillator uses a highly temperature-stable crystal resonator as its frequency reference. This crystal is temperature compensated to reduce the effects of temperature variation on the frequency output of the oscillator. The oscillator is based on a voltage-controlled oscillator (VCO) circuit which consists of a voltage-to- frequency converter and a frequency-dependant filter. The VCO produces a sinusoidal waveform which is then filtered to provide stability and reduce the size of the frequency bandwidth. The VCO output is then compared with the reference frequency to obtain the oscillator’s frequency accuracy and stability.
