ICS83940  
Low Skew, 1-to-18 LVPECL-to-  
LVCMOS/LVTTL Fanout Buffer  
PRODUCT DISCONTINUATION NOTICE - LAST TIME BUY EXPIRES JANUARY 27, 2015  
GENERAL DESCRIPTION  
FEATURES  
The ICS83940 is a low skew, 1-to-18 LVPECL-to-LVCMOS/  
LVTTL Fanout Buffer. The ICS83940 has twoselectable  
clock inputs. The PCLK, nPCLK pair can accept LVPECL,  
CML, or SSTL input levels. The LVCMOS_CLK can accept  
LVCMOS or LVTTL input levels. The low impedance  
LVCMOS/LVTTL outputs are designed to drive 50Ω series  
or parallel terminated transmission lines.  
Eighteen LVCMOS/LVTTL outputs, 16Ω typical output  
impedance  
Selectable LVCMOS_CLK or LVPECL clock inputs  
PCLK, nPCLK supports the following input types:  
LVPECL, CML, SSTL  
LVCMOS_CLK accepts the following input levels:  
LVCMOS or LVTTL  
The ICS83940 is characterized at full 3.3V, full 2.5V and  
mixed 3.3V input and 2.5V output operating supply modes.  
Guaranteed output and part-to-part skew characteristics  
make the ICS83940 ideal for those clock distribution  
applications demanding well defined performance and  
repeatability.  
Maximum output frequency: 250MHz  
Output skew: 150ps (maximum)  
Part to part skew: 750ps (maximum)  
Full 3.3V or 2.5V supply modes  
0°C to 70°C ambient operating temperature  
Industrial temperature information available upon request  
Lead-Free package fully RoHS compliant  
For New Designs Use: 83940DYLF or 83940DYILF
