Abstract:
A burst-mode clock and data recovery circuit using phase selecting technology is provided. In the data recovery circuit, a phase-locked loop (PLL) circuit is used for providing a plurality of fixed clock signals, each of which has a clock phase. An oversampling phase selecting circuit is coupled to the phase-locked loop circuit and used for detecting a data edge of a received data signal by using the clock signals and selects a clock phase to be locked according to the location of the data edge. A delay-locked loop (DLL) circuit is coupled to the phase-locked loop circuit and the oversampling phase selecting circuit, and used for comparing the data phase of the data signal with the clock phase of the selected clock signal, so as to delay the data phase of the data signal by a delay time until the data phase is locked as the clock phase.
