Abstract
A clock data recovery device includes a phase detector circuitry, a signal control circuitry, and interpolators. The phase detector is configured to detect a phase of an input signal, according to first clock signals, to generate first control signals, and phases of the first clock signals are different to each other. The signal control circuitry is configured to rearrange the first control signals to output as second control signals. The phase interpolators are configured to output second clock signals and alternatively adjust the phases of the second clock signals according to the second control signals to generate an output clock signal.
