(1) 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.
(2) See section 3.2 for more current consumption / power dissipation calculation information.
(3) For all frequencies the slew rate, SLEW
CLKin1
, is measured between 20% and 80%.
(4) Specification is guaranteed by characterization and is not tested in production.
(5) The noise floor of the divider is measured as the far out phase noise of the divider. Typically this offset is 40 MHz, but for lower
frequencies this measurement offset can be as low as 5 MHz due to measurement equipment limitations. If the delay is used, then use
section 1.3.
