Abstract:
1. A data recovery system, comprising: an oversampler, which oversamples an input signal for n times and thus generates a plurality of oversampled signals, where n is an integer; a phase detection circuit, which receives the oversampled signals, and outputs a phase signal according to transitions between the oversampled signals; a data pick circuit, which groups the oversampled signals into n groups and picks one of the groups as an output data according to the phase signal, wherein the output data is m-bit and m is an integer; a data overlap/skip detection circuit, which determines a status of the data according to the phase signal and a previous phase signal, and outputs the status; and a data correction circuit, which picks the output data and a last bit of a previous oversampled signal according to the status, and output an accurate data.
