ABSTRACT:
A clock generator in a data receiver for generating an optimum PN code clock used by a spectrum spread (55) communication receiver. The generator comprises a clock generator for generating a plurality of clocks having different phases; a synchronization signal detection circuit for detecting a synchronization signal within a received signal; an optimum clock discrimination circuit for discriminating a first active clock from the plurality of clocks after the synchronization signal detection circuit detected the synchronization signal; and a clock selection circuit for selecting and outputting the clock discriminated from the plurality of clocks by the optimum clock discrimination circuit.
