ICS8533-01 LOW SKEW, 1-TO-4 DIFFERENTIAL-TO-3.3V LVPECL FANOUT BUFFER FEATURES 4 differential 3.3V LVPECL outputs Selectable CLK, nCLK or LVPECL clock inputs CLK, nCLK pair can accept the following differential input levels: LVDS, LVPECL, HSTL, SSTL, HCSL PCLK, nPCLK supports the following input types: LVPECL, CML, SSTL Maximum output frequency up to 650MHz Translates any single-ended input signal to 3.3V LVPECL levels with resistor bias on nCLK input Output skew: 30ps (maximum) Part-to-part skew: 150ps (maximum) Propagation delay: 1.4ns (maximum) 3.3V operating supply 0°C to 70°C ambient operating temperature Industrial temperature information available upon request GENERAL DESCRIPTION The ICS8533-01 is a low skew, high performance 1-to-4 Differential-to-3.3V LVPECL fanout HiPerClockS™ buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8533-01 has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. ,&6 Guaranteed output and part-to-part skew characteristics make the ICS8533-01 ideal for those applications demanding well defined performance and repeatability.
