Abstract

The present invention discloses a method and apparatus for addressing the issue of clock skew in a data signal while making efficient use of space on an integrated chip (IC) by utilizing a physical delay line controlled by a state machine in conjunction with pre-requisite chip architecture. The pre-requisite chip architecture samples the incoming data signal in response to a clocking signal input from the physical delay line; the physical delay line responds to commands from the state machine to increment the delay of the physical delay line to produce samples which describe the incoming data signal and delineate its data valid window.
