Abstract
An apparatus for determining the amount of skew to be injected for system skew compensation in a high-speed data communications system including a plurality of lanes with a data bus per lane. Such skew compensation is necessary due to inherent system skew. By iterating through the possible intervals within the maximum expected skew search space, the correct combination of search space intervals for all lanes can be determined to provide alignment and thus compliancy with relevant standards, such as the SFI-5 and SxI-5 standards, in terms of data skew specifications.
