t
SKD3
, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same V

SKD4
, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over recommended operating
temperature and voltage ranges, and across process distribution. t
