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 VCC = +2.5V, TA = +25°C, and at the Recommended Operating Conditions at
the time of product characterization and are not ensured.
(3)
The total jitter at BER 10-12 is calculated as DJ + (14 x RJ), where DJ is deterministic jitter and RJ is random jitter. The jitter is
expressed as a portion of the unit interval (UI). The UI is the reciprocal of the data rate.
(4)
Specification is ensured by characterization and is not tested in production.
