ABSTRACT:
An arrangement for generating a clock signal. Embodiments provide a method, apparatus, system, and machine-readable medium to interpolate phases of a reference clock signal to output an interpolated clock signal. Some embodiments may output the clock signal as a recovered clock signal for a phase interpolator-based clock recovery system. Many embodiments may interpolate a changing phase of an interpolated clock signal with substantially analog transitions.
