A low phase jitter oscillator which is adjustable in frequency is disclosed. The oscillator comprises a logical OR gate having a feedback loop adjustable in length between the inverted output of the gate and the input of the gate. Using this configuration, the output changes state once every 1/2 T seconds wherein 1/2 T is equal to the propagation delay through the feedback loop and the OR gate. The frequency of the oscillator can be adjusted by adjusting the length of the feedback loop which correspondingly modifies the propagation delay through the feedback loop and thus the frequency of the oscillator output.
