Abstract:
Provided are an apparatus and a method for resetting a transimpedance amplifier for low-power passive optical network equipment for improving the synchronization performance of an uplink burst signal by resetting the transimpedance amplifier for amplifying a received signal of an optical transceiver at a time point at which a frame of the uplink burst signal ends. There is an effect of improving the burst-mode clock and data reconstruction performance through simple analysis of a bit pattern and thus reducing a guard time or a number of repetitions of preambles by accurately identifying the time point at which the frame of the uplink burst signal ends without using a frame data analysis scheme to reset the transimpedance amplifier.

Claim (Index 9):
A method of resetting a transimpedance amplifier for a low-power passive optical network equipment, by which, when a received uplink burst signal is converted into data bit information through a burst-mode clock and data reconstruction process, a reset signal generator generates a reset signal for resetting the transimpedance amplifier included in an optical transceiver based on corresponding data bit information, the method comprising steps of:\n detecting preambles in an appointed bit pattern from the reconstructed data bit information of the uplink burst signal and detecting one or more pieces of frame length information included in appointed locations before a payload of the frame; detecting delimiters in an appointed bit pattern from the reconstructed data bit information of the uplink burst signal and detecting a time point at which the frame ends by comparing a subsequent data bit number with the detected frame length information; and generating a reset signal for resetting the transimpedance amplifier at the detected time point at which the frame ends.
