Working Principle

The SIT3907AC-22-33NX-22.579200Y oscillator is a CMOS based clock source that uses a unique frequency synthesizer and low power architecture in order to ensure its stability in high temperature environments. The working principle is based on the basic properties of an oscillator which is the phase shift between two signals.

The oscillator is based on two voltage signals V1 and V2. When the current voltage of V1 is higher than the current voltage of V2, the phase lead of V1 will gradually increase, pushing the frequency up, while when the voltage of V2 is higher than the voltage of V1, the phase lead of V1 will gradually decrease, thus lowering the frequency. This forms a loop that repeats and the frequency is stabilized at 22.579200Y.

The SIT3907AC-22-33NX-22.579200Y oscillator is also embedded with a frequency discriminator which in terms of its output frequency can detect slight changes and has a fast response time thus preserving the current frequency. It also has a low ripple noise figure, which ensures stability, fidelity and dynamic range of the oscillator.
