Abstract
A phase interpolator (PI) is provided to adjust the phase of a clock such that the phase is aligned to an incoming data pattern from a data stream. The data can be captured from a device such as a flip-flop or the like. The present technique uses a PI (digital to phase) and a digital state machine in a feedback loop to set the correct digital code to the PI inputs to achieve an appropriate clock phase. Of course, there can be variations.
