Abstract:
1. A method for generating a sampling clock signal comprising: storing a predetermined bit pattern, the predetermined bit pattern being a sequence of at least three bits of data; receiving a waveform comprising a series of bits of data; acquiring time-amplitude samples of the waveform wherein the waveform has an edge; detecting an occurrence of the predetermined bit pattern by detecting the sequence of at least three bits of data in the series of bits of data of the waveform based upon the time-amplitude samples; analyzing the time-amplitude samples associated with the predetermined bit pattern responsive to detecting the occurrence of the predetermined bit pattern; adjusting the timing of the sampling clock signal away from the edge of the waveform responsive to analyzing the time-amplitude samples; storing a second predetermined bit pattern; detecting an occurrence of the second predetermined bit pattern; storing time-amplitude samples associated with the second predetermined bit pattern; and readjusting the timing of the sampling clock signal based on the occurrence of the second predetermined bit pattern and the time-amplitude samples associated with the second predetermined bit pattern.
