  • Method and circuit for data regeneration of a data stream
    Patent number: 5905755
    Abstract: Method and circuit for deciding whether or not a pulse in a data stream is or is not a valid pulse of the data stream, wherein a free-running local clock at N-times the data rate is generated and clock pulses thereof are counted once the data stream signal reaches and remains above a slicing threshold. Once a predetermined minimum number of counted clock pulses is attained a valid data pulse signal is issued.
