ABSTRACT:
The invention includes a method and apparatus for aligning a plurality of data channels using a deskew bitstream. The method includes receiving the deskew bitstream, identifying an aligned deskew frame by processing the deskew bitstream, identifying a data channel alignment position associated with each of the plurality of data channels by comparing a deskew channel comparison bit from the aligned deskew frame to a data channel comparison bit from each of the plurality of data channels, and selecting the plurality of data channel alignment positions associated with the respective plurality of data channels for aligning the plurality of data channels. The plurality of data channels are aligned in a manner for substantially reducing skew associated with the data channels. The deskew bitstream comprises a plurality of data bits associated with the data channels and a plurality of parity bits generated using at least a portion of the data bits.
