ABSTRACT:
Disclosed herein is a digital system that includes a distribution network having a path to carry a reference clock and an adjustable delay element disposed along the path, and first and second clock domains coupled to the distribution network to receive the reference clock and configured to be driven by respective clock waveforms, each of which has a frequency in common with the reference clock. The digital system further includes a phase detector coupled to the first and second clock domains to generate a phase difference signal based on the clock waveforms, and a control circuit coupled to the phase detector and configured to adjust the adjustable delay element based on the phase difference signal.
