ABSTRACT:
The invention relates to a data regenerator and an optical receiver with low power consumption. The data regenerator comprises a data decision circuit, a decision parameter generator circuit, a decision parameter control circuit and a power control circuit. The data decision circuit decides data included in an input signal using decision parameters. The decision parameters are generated in the parameter generator. The decision parameters are specified by the parameter control. The parameter control operates only when receiving operating power. The power supply to the parameter control is controlled by the power control. Since power is supplied to the parameter control only when it is necessary to update the parameters, power consumption is reduced.
