(1) Specification is ensured by characterization and is not tested in production.
(2) The Electrical Characteristics tables 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.
(3) Typical values represent most likely parametric norms for V
CC
= +3.3V and T
A
= +25°C, and at the Recommended Operation Conditions
at the time of product characterization and are not ensured.
(4) t
SKD1
, |t
PLHD
− t
PHLD
|, is the magnitude difference in differential propagation delay time between the positive going edge and the negative
going edge of the same channel.
(5) t
SKD2
, Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This
specification applies to devices at the same V
CC
and within 5°C of each other within the operating temperature range.
