PROBLEM TO BE SOLVED: To provide a data recovery circuit having a sampling frequency less than a data clock frequency. SOLUTION: A method and related circuit for recovering a digital signal can operate with a sampling frequency less than a data frequency. The circuit includes a plurality of interpolators for generating an output signal. The output signal is used by a computation module to generate a plurality of control words. The control words are used by the interpolators to perform weighted interpolation functions to precisely generate the output signal. A data circuit can then extract the original input signal digital information from the output signal. COPYRIGHT: (C)2003,JPO
