Abstract
A steering current generator for a phase interpolator has a multiplicity of fine phase adjustment current sources, each of which is switchable to direct its current to one or other of two summing nodes. The current of each of those two summing nodes is supplemented by respective fixed always-on current sources. The steering current generator has four current outputs and a switching matrix is provided to switch the current from the summing nodes to first and second selected ones of those outputs. The switching matrix is also connected to switch bleed currents to the other two of the current outputs.
