Integrated circuit with timing adjustment mechanism and method

Abstract

An integrated circuit device includes a receiver, a register and a clock circuit. The receiver samples data from an external signal line in response to an internal clock signal. The register stores a value that represents a timing offset to adjust the time at which the data is sampled. The clock circuit generates the internal clock signal such that the internal clock signal maintains a controlled timing relationship with respect to an external clock signal. The clock circuit includes an interpolator that phase mixes a set of reference clock signals such that the internal clock signal is phase offset in accordance with the value.
