www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS85311 Low Skew, 1-to-2 Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer FEATURES 2 differential 2.5V/3.3V LVPECL / ECL outputs 1 CLK, nCLK input pair CLK, nCLK pair can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL Maximum output frequency up to 1GHz Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLK input Output skew: 15ps (maximum) Part-to-part skew: 100ps (maximum) Propagation delay: 1.4ns (maximum) LVPECL mode operating voltage supply range: VCC = 2.375V to 3.465V, VEE = 0V ECL mode operating voltage supply range: VCC = 0V, VEE = -2.375V to -3.465V 0°C to 70°C ambient operating temperature Industrial temperature information available upon request GENERAL DESCRIPTION The ICS85311 is a low skew, high performance 1-to-2 Differential-to-2.5V/3.3V ECL/ HiPerClockS™ LVPECL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The CLK, nCLK pair can accept most standard differential input levels.T h e ICS85311 is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and partto-part skew characteristics make the ICS85311 ideal for those clock distribution applications demanding well defined performance and repeatability. ,&6 BLOCK DIAGRAM CLK nCLK Q0 nQ0 Q1 nQ1 PIN ASSIGNMENT Q0 nQ0 Q1 nQ1 1 2 3 4 8 7 6 5 Vcc CLK nCLK VEE ICS85311 8-Lead SOIC ...
