(1) 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.
(2) Typical values represent most likely parametric norms at V_DD = 3.3V, T_A = 25°C, and at the Recommended Operation Conditions at the
time of product characterization and are not ensured.
(3) Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground
except VOD and ΔVOD, which are differential voltages.
(4) Specification is ensured by characterization and is not tested in production.
(5) Specification is ensured by design and is not tested in production.
(6) UI – Unit Interval is equivalent to one serialized data bit width (1UI = 1 / 35*PCLK). The UI scales with PCLK frequency.
