Zusammenfassung:A system for compensating for periodic noise in a time interleaved system having multiple phases of interest includes a master clock path, a detection circuit and an actuator circuit. The master clock path is configured to receive an input clock and to output an output clock, each of the input and output clocks having periodically occurring interleaving periods. Each interleaving period includes timeslots corresponding to the phases of interest of the time interleaved system. The detection circuit is configured to receive the input and output clocks for each timeslot, and to detect periodic noise in the output clock introduced by the master clock path by comparing the received input and output clocks. The actuator circuit includes a controllable delay element configured to adjust a delay of the input clock through the master clock path to compensate for the periodic noise detected by the detection circuit for each timeslot.
