ABSTRACT:
A data recovery device using a sampling clock with a half frequency of data rate is disclosed, which includes a phase detection circuit, a charge pump and a double clock frequency oscillation circuit. The phase detection circuit receives a data signal and a first clock signal for generating an up-adjustment signal and a down-adjustment signal. The charge pump generates a control voltage in accordance with the up- and down-adjustment signals. The double clock frequency oscillation circuit receives the control voltage for generating the first clock signal with adjustment phase. The invention uses the sampling clock with a half frequency of the data rate not only reduces the die size, but also reduces the power consumption.
