Abstract
A system and method for effectively supporting a data transmission procedure includes a phase interpolator with a modular array of unit phase interpolators that each receives a respective input clock signal that is phase-shifted with respect to other input clock signals received by the remaining unit phase interpolators. The unit phase interpolators responsively generate corresponding UPI output signals that are summed together to produce a receiver clock signal. The phase interpolator receives a phase control word that includes a UPI selection segment and a UPI output-control segment. The phase interpolator utilizes the UPI selection segment to selectively activate pairs of the unit phase interpolators. The phase interpolator also utilizes the UPI output-control segment for controlling the UPI output signals to thereby adjust phase characteristics of the receiver clock signal.
