ABSTRACT:
Disclosed is a device for recovering a burst-mode clock. The burst-mode clock recovery device includes a delay unit and a logic element. A reference clock is produced by implementing a logic operation with respect to a signal output from signal forming device and a signal output from the signal forming device and delayed by a delay unit. A duty of a final output signal is corrected by implementing and AND operation with respect to the generated reference clock and an output from feedback device.
