Abstract
An apparatus includes a plurality of coarse delay circuits and a phase blender circuit. The coarse delay circuits may be configured to (i) receive an input clock signal, (ii) receive a plurality of control signals and (iii) generate a first phase signal and a second phase signal. The phase blender circuit may be configured to (i) receive the first phase signal and the second phase signal, (ii) receive a phase control signal, (iii) step between stages implemented by the coarse delay circuits and (iv) present an output clock signal. The phase blender circuit may mitigate a mismatch between the stages of the coarse delay circuits by interpolating an amount of coarse delay provided by the coarse delay circuits.
