2.14.3. TSG-03 : Differential Skew
2.14.3.1. Device/Host Expected Behavior
See section 7.2.2.3.4 of Serial ATA Revision 2.6.
See section 7.4.12 of Serial ATA Revision 2.6.
Measurement Requirements
This test is only run once at the maximum interface rate of the product (1.5Gb/s or 3Gb/s).
DC blocks or software/hardware equivalent shall be used.
Please note that this requires measuring the mean skew of TX+ rise mid-point to the TX- fall mid-point and
the mean skew of TX+ fall mid-point to TX- rise mid-point, as stated in 7.2.2.3.4, and then computing the
Differential Skew = average of the magnitude (absolute value) of the two mean skews. This removes the
effect of rise-fall imbalance from the skew measurement.

measured at a maximum of 20 ps
Pass/Fail Criteria
The value above shall be based on at least 10,000 UIs
