Patent ID: 7039328

Claim:
A data regenerator for outputting a regenerated signal by receiving input electrical signals including a data component and a clock component synchronized to the data component, comprising: a first data decision circuit, by receiving the data component, the clock component and a first decision parameter signal, for outputting the regenerated signal; a parameter control circuit, by receiving the data component, the clock component and an operating power, for outputting a parameter control signal to a first parameter generator circuit, the parameter control circuit comprising: a second data decision circuit, by receiving the data component, the clock component and a second decision parameter signal, for outputting a decision signal, an error detection circuit, by receiving the decision signal, for calculating a bit error rate, and a variable decision parameter generator circuit including a controller and a second parameter generator circuit, the controller outputting the parameter control signal by receiving the bit error rate output from the error detection circuit, the second parameter generator circuit outputting the second decision parameter signal to the second data decision circuit by receiving the parameter control signal from the controller; said first parameter generator circuit, by receiving the parameter control signal from the parameter control circuit and outputting the first decision parameter signal corresponding to the parameter control signal to the first data decision circuit; and a power control circuit, by receiving the input signal, for controlling the operating power to the parameter control circuit.
