Abstract
A data recovery apparatus and method for receiving at least an original clock and at least an original data stream output from a transmitter to output at least one recovery data are provided. The original data stream and the recovery data respectively include N steps in a period T of the original clock, wherein N is an integer larger than 0. The data recovery apparatus includes a sampling unit and a processing unit. The sampling unit samples the original data stream according to the original clock, wherein the sampling unit samples the corresponding data of the original data stream at least three times with T/(4N) sample period in each step. The processing unit receives and compares the sampled result output from the sampling unit, and recovers the sampled result to the recovery data according to the compared result.
