Notes:

7.

Measured from the differential input crossing point to the differential output crossing point.

8.

Output-to-Output skew is the difference in time between outputs, receiving data from the same input, for the same temperature, voltage and

transition.

9.

Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the respective

inputs.

10. This parameter is defined in accordance with JEDEC Standard 65.
