Abstract
The present disclosure provides a clock data recovery circuit that includes a phase locked loop unit, a delay locked loop unit and digital clock data recovery unit. The phase locked loop unit generates a clock signal based on a reference signal. The delay locked loop unit receives the clock signal from the phase locked loop, divides the clock signal into a plurality of clock signals and outputs the clock signals. The digital clock data recovery unit receives an input current signal, estimates a frequency of the input current signal, outputs a reference signal having the frequency, which can be transmitted to the phase locked loop unit, receives the clock signals from the delay locked loop, aligns a phase of the input current signal based on the clock signals and outputs an aligned current signal.
