Does Altera ALTGX PHY allows lane reversal for a XAUI link (lane 0 to lane 3, lane 1 to lane 2, and so on)? - Does Altera ALTGX PHY allows lane reversal for a XAUI link (lane 0 to lane 3, lane 1 to lane 2, and so on)? Description Lane reversal is not an option at the PHY layer of the high speed GX/GT/GZ transceivers. You'll need to connect the lanes in sequence (0-to-0, 1-to-1, 2-to-2 and 3-to-3).
