Abstract
A non-linear phase detector includes a retiming stage and a phase synchronization stage. The retiming stage is coupled to a data signal and a recovered clock signal. The retiming stage is triggered by the recovered clock signal and samples the data signal to generate a retimed data signal and a clock synchronization signal. The phase synchronization stage is coupled to the retimed data signal and the clock synchronization signal. The phase synchronization stage is triggered by the retimed data signal and samples the clock synchronization signal to generate a phase control signal.
