HIGH SPEED DIGITAL DATA RETIMING DEVICE

摘要

PURPOSE: An apparatus for re-timing high-speed digital data is provided to re-time data without loss of the data by providing the apparatus for re-timing high-speed digital data having large range for input allowable jitter. CONSTITUTION: A clock pulse generator(100) generates n multiple delay clock pulses having n phases. A transition detector(200) generates and outputs data transition detection signals which select one or more clock pulses where transition is generated. A data transition detection signal monitor(300) monitors the data transition detection signal and generates a clock pulse control signal. A D flipflop(500) re-times the serial data inputted form exterior to the clock pulse mixed by a clock pulse mixer(400). A re-timing buffer(600) re-times the re-timed data to the clock from exterior to synchronize and output it with external clock.
