DESCRIPTION

The CDCLVC11xx isa modular,high-performance,low-skew,generalpurpose clockbufferfamilyfrom Texas Instruments. The whole familyisdesignedwitha modularapproachinmind.Itisintendedtoroundup TI's seriesofLVCMOS clockgenerators. There are7 differentfan-outvariations,1:2to1:12,available.Allofthedevicesarepincompatibletoeach other foreasy handling. Allfamilymembers share the same highperformingcharacteristicslikelow additivejitter,low skew, and wide operatingtemperaturerange. The CDCLVC11xx supportsan asynchronousoutputenablecontrol(1G) which switchestheoutputsintoa low statewhen 1G islow.Also,versionswithsynchronizedenablecontrolforglitchfreeswitchingand three-state outputsareplannedinfuturedeviceoptions. The CDCLVC11xx operateina 2.5V and 3.3V environmentand arecharacterizedforoperationfrom–40°C to 85°C.

www.ti.com 26-Jun-2010 Addendum-Page 2 (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
