ICS8701-01  
LOW SKEW ¸1, ¸2 CLOCK  
Integrated  
Circuit  
Systems, Inc.  
GENERATOR W/POLARITY CONTROL  
GENERAL DESCRIPTION  
FEATURES  
The ICS8701-01 is a low skew, ÷1, ÷2 Clock • 20 LVCMOS outputs, 7typical output impedance  
,&6  
Generator and a member of the HiPerClockS™  
family of High Performance Colck Solutions  
• Output frequency up to 250 MHz  
HiPerClockS™  
from ICS. The low impedance LVCMOS outputs  
are designed to drive 50series or parallel ter-  
• 250ps bank skew, 300ps output skew, 350ps multiple  
frequency skew, 700ps part-to-part skew  
minated transmission lines. The effective fanout can be in-  
creased from 20 to 40 by utilizing the ability of the outputs to  
drive two series terminated lines.  
• Selectable inverting and non-inverting outputs  
• LVCMOS / LVTTLclock 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 master reset/  
output enable input, nMR/OE, resets the internal dividers and  
controls the active and high impedance states of all outputs.  
The output polarity inputs, INV0:1, control the polarity (invert-  
ing or non-inverting) of the outputs of each bank. Outputs  
QA0-QA4 are inverting for every combination of the INV0:1  
input. The timing relationship between the inverting and non-  
inverting outputs at different frequencies is shown in the Tim-  
ing Diagrams.  
• LVCMOS / LVTTLcontrol inputs  
• Bank enable logic allows unused banks to be disabled  
in reduced fanout applications  
• 3.3V or mixed 3.3V input, 2.5V output operating  
supply modes  
• 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  
• Other divide values available on request  
The ICS8701-01 is characterized at 3.3V and mixed 3.3V in-  
put supply, and 2.5V output supply operating modes. Guar-  
anteed bank, output and part-to-part skew characteristics  
make the ICS8701-01 ideal for those clock distribution appli-  
cations demanding well defined performance and repeatabil-  
ity.
