(1) The Electrical Characteristics list ensured specifications under the listed Recommended Operating Conditions except as otherwise
modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not
ensured.
(2) Typical values represent most likely parametric norms for VDD = +3.3V and TA = +25°C, and at the Recommended Operating Conditions
at the time of product characterization and are not ensured.
(3) CL includes fixture capacitance and CD includes probe capacitance.
(4) Specification is specified by characterization and is not tested in production.
(5) tSKD1, |tPLHD − tPHLD|, Pulse Skew, is the magnitude difference in differential propagation delay time between the positive going edge and
the negative going edge of the same channel.
(6) tSKD2, Channel-to-Channel Skew, is the difference in propagation delay (tPLHD or tPHLD) among all output channels.
(7) tSKD3, Part-to-Part Skew, is defined as the difference between the minimum and maximum differential propagation delays. This
specification applies to devices at the same VDD and within 5°C of each other within the operating temperature range.
(8) tSKD4, 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. tSKD4 is defined as |Max − Min|
differential propagation delay.
