(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

1. Measurements based on an ideal input with zero intra-pair skew on the input, i.e. the input at A to B/C or the input at B/C to A
2. Inter-pair skew is measured from lane to lane on the same channel, e.g. C0 to C1
3. Intra-pair skew is defined as the relative difference from the p and n signals of a single lane
