ABSTRACT:
A noise-resistive, burst-mode receiving apparatus including a voltage control signal generator for multiplying a frequency of a system clock signal and generating a voltage control signal having a level that corresponds to the multiplied frequency; a reset signal generator for delaying an irregular input signal in the unit of a packet, in response to the voltage control signal, performing an exclusive OR operation on the delayed and input signals, and outputting the result as a reset signal; a clock signal generator for generating a signal having a level that is changed at the middle point of each bit included in the packet as a recovered clock signal in response to the reset signal and the voltage control signal and outputting the recovered clock signal; and an output buffer for buffering the input signal and outputting the buffered signal as recovered data in response to the recovered clock signal.
