摘要: The present invention discloses a method and apparatus for addressing the issue of clock skew in a data signal while making efficient use of space on an integrated chip (IC) by utilizing a physical delay line controlled by a state machine in conjunction with pre-requisite chip architecture. The pre-requisite chip architecture samples the incoming data signal in response to a clocking signal input from the physical delay line; the physical delay line responds to commands from the state machine to increment the delay of the physical delay line to produce samples which describe the incoming data signal and delineate its data valid window.

摘要: An apparatus for determining the amount of skew to be injected into a high-speed data communications system of including a plurality of lanes having a data bus per lane, relative to a reference lane, for system skew compensation. By knowing the relative amount of skew that each lane requires for alignment, an appropriate amount of skew can be injected on each lane to provide alignment and thus compliancy with the SFI-5 and SxI-5 standards, in terms of data skew specifications. The relative skew amounts for each transmitting lane are determined using a methodology involving internal loopback and characteristics from a connected communications element to the chip receive path.

摘要: 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.

摘要: This algorithm and apparatus provides the ability to determine the amount of skew that should be injected into a high-speed data communications system consisting of a plurality of lanes comprising a data bus on a per lane basis, relative to a reference lane, for the purpose of compensating for inherent system skew. By knowing the relative amount of skew that each lane requires for alignment, an appropriate amount of skew can then be injected on each lane to provide alignment and thus compliancy with relevant standards, such as the Sxl-5 standard, in terms of data skew specifications. These relative skew amounts for each transmitting lane are determined using a methodology involving internal loopback and characteristics from the connected communications element to the chip receive path.
