ABSTRACT:
A received data recovering device that can follow a rapid change in phase of data in data communication, thereby to prevent lowering of the data transmission efficiency, samples a baseband signal in a shift register group of a clock phase detecting circuit using an N-times (N is an integer equal to or greater than 2) frequency relative to the baseband signal, and outputs to a field phase detecting circuit the number of bits required by each of fields per N, the field phase detecting circuit detecting not only a synchronization word, but also error data with respect to fields of a packet header and a Forward Error Correction (FEC) code depending on existence of data and outputting optimum clock phase information to a First In First Out (FIFO).
