Abstract
A circuit for recovering a clock signal may include a frequency multiplier configured to generate a plurality of local clock signals, each having a different phase, based on a plurality of received global clock signals at a first frequency and each having a different phase. The local clock signals may be generated at a second frequency higher than the first frequency. The circuit may include a phase interpolator configured to generate a recovered clock signal at a given phase and at a third frequency, based on the generated local clock signals, and a phase shifter configured to adjust the phase of the recovered clock signal so as to synchronize the phase of the recovered clock signal with a phrase of input data that is input to the phase shifter.
