ICS87974I  
LOW SKEW, 1-TO-15,  
LVCMOS/LVTTL CLOCK GENERATOR  
Integrated  
Circuit  
Systems, Inc.  
GENERAL DESCRIPTION  
FEATURES  
Fully integrated PLL  
The ICS87974I is a low skew, low jitter 1-to-15  
ICS  
LVCMOS/LVTTL Clock Generator/Zero Delay  
Buffer and is a member of the HiPerClockS™  
family of high performance clock solutions from  
ICS. The device has a fully integrated PLL and  
HiPerClockS™  
Fifteen single ended 3.3V LVCMOS/LVTTL outputs  
Two LVCMOS/LVTTL clock inputs for redundant clock  
applications  
three banks whose divider ratios can be independently con-  
trolled, providing output frequency relationships of 1:1, 2:1,  
3:1, 3:2, 3:2:1. In addition, the external feedback connec-  
tion provides for a wide selection of output-to-input fre-  
quency ratios. The CLK0 and CLK1 pins allow for redun-  
dant clocking on the input and dynamically switching the  
PLL between two clock sources.  
CLK0 and CLK1 accepts the following input levels:  
LVCMOS/LVTTL  
Output frequency range: 8.33MHz to 125MHz  
VCO range: 200MHz to 500MHz  
External feedback for ”zero delay” clock regeneration  
Cycle-to-cycle jitter: 100ps ꢀtypicalꢁ  
Output skew: 350ps ꢀmaximumꢁ  
Guaranteed low jitter and output skew characteristics make  
the ICS87974I ideal for those applications demanding well  
defined performance and repeatability.  
3.3V operating supply  
-40°C to 85°C ambient operating temperature  
Available in both standard and lead-free RoHS-compliant  
packages
