Note 11: The Electrical Characteristics tables list guaranteed 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 guaranteed.
Note 12: Typical values represent most likely parametric norms for V_DD = +3.3V and T_A = +25°C, and at the Recommended Operation Conditions at the time of
product characterization and are not guaranteed.
Note 13: Specification is guaranteed by characterization and is not tested in production.
Note 14: t_SKD1, |t_PLHD − t_PHLD|, 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.
Note 15: t_SKD2, Channel-to-Channel Skew, is the difference in propagation delay (t_PLHD or t_PHLD) among all output channels.
Note 16: t_SKD3, 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 V_DD and within 5°C of each other within the operating temperature range.
Note 17: t_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_SKD4 is defined as |Max − Min| differential propagation delay.
Note 18: C_L includes fixture capacitance and C_D includes probe capacitance.
