www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS8530 LOW SKEW, 1-TO-16 DIFFERENTIAL-TO-2.5V LVPECL FANOUT BUFFER FEATURES 16 differential 2.5V LVPECL outputs CLK, nCLK input pair CLK, nCLK pair can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL Maximum output frequency up to 500MHz Translates any single-ended input signal to 2.5V LVPECL levels with a resistor bias on nCLK input Output skew: 50ps (maximum) Part-to-part skew: 250ps (maximum) Propagation Delay: 2ns (maximum) 3.3V core, 2.5V output operating supply 0°C to 70°C ambient operating temperature Industrial temperature information available upon request GENERAL DESCRIPTION The ICS8530 is a low skew, 1-to-16 Differential,&6 to-2.5V LVPECL Fanout Buffer and a member of HiPerClockS™ the HiPerClockS™ family of High Performance Clock Solutions from ICS. The CLK, nCLK pair can accept most standard differential input levels. The high gain differential amplifier accepts peak-to-peak input voltages as small as 150mV, as long as the common mode voltage is within the specified minimum and maximum range. Guaranteed output and part-to-part skew characteristics make the ICS8530 ideal for those clock distribution applications demanding well defined performance and repeatability.
