ELIMINATING CLOCK SKEW BY USING BIDIRECTIONAL SIGNALING

摘要

A clock signal distribution circuit including: a signal transmission system having first and second signal transmission lines, each extending from the first end to the second end of the signal transmission system, the first signal transmission line for carrying a first periodic signal from the first end to the second end of the signal transmission system, the second signal transmission line for carrying a second periodic signal from the second end to the first end of the signal transmission system transmission; and a local clock signal generator circuit including a detector system for detecting at a preselected location along the signal transmission system the first and second periodic signals, wherein the generator circuit generates from both the detected first and second periodic signals a local clock signal that has a predetermined skew that is between to the skews of the detected first and second periodic signals.
