ICS8501

Integrated Circuit Systems, Inc. LOW SKEW 1-TO-16 DIFFERENTIAL CURRENT MODE FANOUT BUFFER FEATURES 16 small swing DCM outputs Translates any differential input signal(PECL, HSTL, LVDS, DCM) to DCM levels without external bias networks Translates single ended input levels to DCM levels with a resistor bias network on the nCLK input Translates single ended input levels to inverted DCM levels with a resistor bias network on the CLK input Voh(max) = 1.2V 40% of Voh ≤ Vcrossover ≤ 60% of Voh 45% ≤ Duty Cycle ≤ 55% Output frequency up to 500MHz 100ps output skew 3.3V operating supply 48 lead low-profile QFP(LQFP), 7mm x 7mm x 1.4mm package body, 0.5mm package lead pitch 0°C to 70°C ambient operating temperature ICS8501 The ICS8501 is a low skew, 1-to-16 Differential Current Mode Fanout Buffer and a member of HiPerClockS™ the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8501 is designed to translate any differential signal levels to small swing differential current mode(DCM) output levels. An external reference resistor is used to set the value of the current supplied to an external load load/termination resistor. The load resistor value is chosen to equal the value of the characteristic line impedance of 50Ω. The ICS8501 is characterized at an operating supply voltage of 3.3V. GENERAL DESCRIPTION ,&6 The small swing outputs, accurate crossover voltage and duty cycle makes the ICS8501 ideal for interfacing to today’s most adva...
