    摘要: Burst mode clock and data recovery (BCDR) circuit and method capable of fast data recovery of passive optical network (PON) traffic. An over-sampled data stream is generated from an input burst data signal and a phase interpolator generates sampling clock signals using a reference clock and phase information. A phase estimation unit (PEU) determines a phase error in the over-sampled data streams; and a phase retrieval unit sets the phase interpolator with the respective phase information of the input burst data signal prior to reception of the input burst data signal.
