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