Abstract
A phase interpolator is provided that, in one implementation, includes first and second interpolator modules, each having an output in communication with an output node. The first interpolator includes an input to receive a first plurality of input phase signals, and a selector to select one or more of the first plurality of input phase signals for interpolation at the output node of the phase interpolator. The second interpolator module includes an input to receive a second plurality of input phase signals, and a selector to select one or more of the second plurality of input phase signals for interpolation at the output node of the phase interpolator. Each of the selected ones of the first plurality of input signals and each of the selected ones of the second plurality of input signals are included in an interpolated output signal.
