Abstract

Embodiments of a device and circuit implementing a digitally controlled oscillator with reduced analog components. In an example, the digitally controlled oscillator can include a phase accumulator controlled by a stall circuit to selective stall the phase accumulator. In some examples, the digitally controlled oscillator can include a phase select circuit to select multiple phases of a phase select circuit based on the output of the phase accumulator. In some examples, these selected phases can then be used by a phase interpolator to generate a synthetic clock signal.
