Robust and scalable de-skew method and apparatus for data path skew control

摘要

A method for selectively deskewing data traveling through a bus in a network device is disclosed. Bit-level data is received from each data line of a plurality of data lines of the bus. Vertical line information is detected for the plurality of data lines to determine if there is a match with a training pattern. A skew distance is calculated once there is a match with the training pattern. Then, the plurality of data lines are bit aligned based on the skew distance.
