www.DataSheet4U.com PRELIMINARY Integrated Circuit Systems, Inc. ICS85314-01 LOW SKEW, 1-TO-5 DIFFERENTIAL-TO-2.5V/3.3V LVPECL FANOUT BUFFER FEATURES 5 differential 2.5V/3.3V LVPECL outputs Selectable differential CLK0, nCLK0 or LVCMOS inputs CLK0, nCLK0 pair can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL CLK1 can accept the following input levels: LVCMOS or LVTTL Maximum output frequency: 650MHz Translates any single-ended input signal to 3.3V LVPECL levels with resistor bias on nCLK input Output skew: 50ps (maximum) Part-to-part skew: 400ps (maximum) Propagation delay: CLK0, nCLK0 - 2.1ns (maximum) CLK1 - 2.1ns (maximum) LVPECL mode operating voltage supply range: VCC = 2.375V to 3.8V, VEE = 0V -40°C to 85°C ambient operating temperature Compatible to part number MC100LVEL14 GENERAL DESCRIPTION The ICS85314-01 is a low skew, high performance 1-to-5 Differential-to-3.3V LVPECL fanout buffer HiPerClockS™ and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85314-01 has two selectable clock inputs. The CLK0, nCLK0 pair can accept most standard differential input levels. The single-ended CLK1 can accept LVCMOS or LVTTL input levels. The clock enable is internally synchronized to eliminate runt clock pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. ,&6 Guaranteed output and part-to-part skew characteristics make the ICS85314-01 ideal ...
