ABSTRACT:
A system and method for bit eye center determination is provided. In general, the system samples an incoming data stream to determine where transitions in the data stream occur, selectively offsets the selected samples based on state criteria and the number of transitions in each set of samples, accumulates the offset samples and averages the result to determine the center of the bit eye. The system and method also provides the ability to locate the eye center even in the case of noise in the system, whether the noise is random or deterministic, including odd/even noise.
