ABSTRACT:
A data recovery device. The device adjusts a digital signal according to a pulse signal output by a phase-locked loop circuit. The sampling circuit samples each bit of the digital signal five times to generate a first sampled signal. The data delay buffer decides a sampling range of the first sampled signal and outputs a second sampled signal. The sampling range selector picks a part of bits of the second sampled signal and outputs output data. The weighted detecting module outputs a phase shifting signal responding to the output data. The first loop filter outputs a first adjusting signal. The first sampling window module outputs a phase selecting signal. The second loop filter outputs the recovery signal and a second adjusting signal. The second sampling window module outputs the first phase checking signal and the second phase checking signal. The phase picking module outputs the output data.
