Abstract
A method and apparatus for providing high speed, linear-phase interpolation. Signals from a plurality of differential pairs are weighted to produce an output clock having a selectable linear phase variation. A controller includes a pulse generator for providing a predetermined number of pulses having a predetermined phase shift and a predetermined frequency and an interpolator for processing the predetermined number of pulses having a predetermined phase shift and a predetermined frequency to generate a clock signal that is linearly adjustable between a predetermined number of output phases.
