Patent ID: 7936193

Claim:
A multi-phase clock system for receiving a plurality of clock signals comprising actual time events defining different clock phases, the clock signals all having a same clock frequency but different clock phases, the system further being arranged for receiving a reference clock signal for providing reference time events for the clock signals, the reference clock signal having a reference frequency different from the clock frequency, the reference frequency being selected such that each one of the subsequent reference time events coincides with a desired time event for a single one of the clock signals, the system comprising: a comparator arranged for sequentially comparing corresponding ones of the reference time events and the actual time events for sequentially generating a plurality of timing difference indicators, and a de-skew circuit for de-skewing a corresponding one of the clock signals with respect to the reference clock signal in response to the corresponding timing difference indicator to obtain corrected clock signals having actual time events coinciding with the corresponding reference time events.
