Abstract:
A clock distribution and alignment system includes at least three clock generators, each including a clock receiver circuit to receive a first clock signal having a first frequency, and a clock divider circuit to divide the received first clock signal into a second clock signal having a second frequency lower than the first frequency, each of two or more of the clock generators further including a phase detector circuit to compare the phase of the second clock signal with the phase of the second clock signal for a next one of the clock generators, and a clock adjuster circuit to adjust the phase of the received first clock signal based on the compared phases of the second clock signals. In some cases, the clock adjuster circuit is further to align the phases of the second clock signals to within a predefined tolerance of each other.
