ABSTRACT:
An oversampling data recovery circuit for a receiver comprises a plurality of sampling circuits for sampling an input data upon a plurality of clocks to generate a plurality of sample data, respectively, an edge detector for determining an edge of the input data by monitoring the plurality of sample data, and a state machine for selecting one from the plurality of sample data as an output data of the oversampling data recovery circuit according to the edge of the input data, such that the receiver will have an optimum timing margin.
