''A SYNCHRONOUS RECEIVING METHOD AND THE CIRCUIT OF HIGH SPEED SERIAL BURST DATA IN OPTICAL COMMUNICATION SYSTEM

摘要

The invention discloses a method and circuit that is a high-speed receiving method and circuit with fast bit synchronization receiving using multiphase clock. The method includes: taking clocks with X.different phases to over-sample highspeed and burst uplink data and obtaining X paths data that are adapted to the local clock; detecting the preamble codes of the X paths data that having been adapted to the local clock to determine a received correct data; and selecting the correct data being sampled by the clock positioned at middle of eye pattern, and making serial-parallel conversion, byte and cell synchronization.
