ICS8702  
Integrated  
Circuit  
Systems, Inc.  
LOW SKEW, ÷1, ÷2  
DIFFERENTIAL-TO-LVCMOS/LVTTL CLOCK GENERATOR  
GENERAL DESCRIPTION  
FEATURES  
The ICS8702 is a low skew, ÷1, ÷2 Differential-to- Twenty LVCMOS outputs, 7Ω typical output impedance  
ICS  
HiPerClockS™  
LVCMOS Clock Generator and a member of the  
• One differential clock input pair  
HiPerClockSfamily of High Performance Clock  
Solutions from ICS. The ICS8702 is designed to  
translate any differential signal levels to  
• CLK, nCLK supports the following input types:  
LVDS, LVPECL, LVHSTL, SSTL, HCSL  
LVCMOS/LVTTL levels. True or inverting, single-ended to  
LVCMOS translation can be achieved with a resistor bias  
on the nCLK or CLK inputs, respectively. The effective fan-  
out can be increased from 20 to 40 by utilizing the ability of  
the outputs to drive two series terminated lines.  
• Maximum output frequency: 250MHz  
Translates any differential input signal (LVPECL, LVHSTL,  
LVDS) to LVCMOS levels without external bias networks  
Translates any single-ended input signal to LVCMOS levels  
with a resistor bias on nCLK input  
The divide select inputs, DIV_SELx, control the output fre-  
quency of each bank.The outputs can be utilized in the ÷1, ÷2  
or a combination of ÷1 and ÷2 modes. The bank enable in-  
puts, BANK_EN0:1, supports enabling and disabling each  
bank of outputs individually.The master reset input, nMR/OE,  
resets the internal frequency dividers and also controls the  
enabling and disabling of all outputs simultaneously.  
• Bank enable logic allows unused banks to be disabled in  
reduced fanout applications  
Output skew: 200ps (maximum)  
Bank skew: 150ps (maximum)  
Part-to-part skew: 650ps (maximum)  
Multiple frequency skew: 250ps (maximum)  
The ICS8702 is characterized at 3.3V and mixed 3.3V input  
supply, and 2.5V output supply operating modes. Guaranteed  
bank, output, multiple frequency and part-to-part skew char-  
acteristics make the ICS8702 ideal for those clock dis-  
tribution applications demanding well defined performance  
and repeatability.  
• 3.3V or mixed 3.3V input, 2.5V output operating  
supply modes  
• 0°C to 70°C ambient operating temperature  
• Other divide values available on request  
• Available in both standard and lead-free RoHS compliant  
packages
