| Integrated Circuit Systems, Inc. ICS8501 LOW SKEW, 1-TO-16 DIFFERENTIAL CURRENT MODE FANOUT BUFFER 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 de- signed 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/termination resistor. The load resistor value is chosen to equal the value of the characteristic line impedance of The ICS8501 is char- acterized at an operating supply voltage of 3.3V. The small swing outputs, accurate crossover voltage and duty cycle makes the ICS8501 ideal for interfacing to today’s most advanced microprocessors. • 16 small swing DCM outputs • Translates any differential input signal LVPECL, LVHSTL, 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 • Maximum output frequency 500MHz • Output skew 100ps maximum • Part-to-part skew 650ps maximum • VOH 850mV maximum • 3.3V operating supply • 0°C to 70°C ambient operating temperature BLOCK DIAGRAM CLK nCLK Q0 nQ0 Q1 nQ1 Q2 nQ2 Q3 nQ3 Q4 nQ4 Q5 nQ5 Q6 nQ6 Q7 nQ7 8501BY PIN ASSIGNMENT nCLK VDD Q15 nQ15 Q14 nQ14 GND Q13 nQ13 Q12 nQ12 Q15 nQ15 Q14 nQ14 Q13 nQ13 Q12 nQ12 TABLE ORDERING INFORMATION Part/Order Number ICS8501BY ICS8501BYT Marking ICS8501BY ICS8501 LOW SKEW, 1-TO-16 DIFFERENTIAL CURRENT MODE FANOUT BUFFER Package 48 Lead LQFP 48 Lead LQFP on Tape and Reel Count 250 per tray 1000 Temperature 0°C to 70°C 0°C to 70°C While the information presented herein has been checked for both accuracy and reliability, Integrated Circuit Systems, Incorporated ICS assumes no responsibility for either its use or for infringement of any patents or other rights of third parties, which would result from its use.
