摘要: An integrated circuit includes clock deskew circuitry. The deskew circuitry includes multiple loop circuits to align a received clock with a data eye, and to reduce the effects of clock drift caused by voltage and temperature variations. The loop circuits include phase interpolators to produce local clock signals. Local clock signals are provided to seqiuential elements through local clock trees and are also provided to a phase detector through a dummy local clock tree. The operation of the phase interpolators is influenced by the phase detector.
