Digital delay-locked loop circuits with hierarchical delay adjustment
Fine tuned signal phase adjustments are provided by multiple cascaded phase mixers. Each phase mixer outputs a signal having a phase between the phases of its two input signals. With each subsequent stage of phase mixers, the signals generated by the phase mixers have a smaller phase difference, thereby providing finer delay adjustments. Multiple stages of phase mixers can be provided in digital delay-locked loop circuitry to provide additional hierarchical delay adjustment.
