DATASHEET  
QUAD DIFFERENTIAL PCI-EXPRESS CLOCK SOURCE  
ICS557-05A  
Description  
Features  
The ICS557-05A is a spread-spectrum clock generator that  
supports PCI-Express requirements. It is used in PC or  
embedded systems to substantially reduce  
electro-magnetic interference (EMI). The device provides  
four differential HCSL or LVDS high-frequency outputs with  
spread spectrum capability. The output frequency and  
spread type are selectable using external pins.  
Packaged in 20-pin TSSOP  
Available in RoHS 5 (green) or RoHS 6 (green and lead  
free) complaint package  
Supports PCI-Express applications  
Four differential spread spectrum clock outputs  
Spread spectrum for EMI reduction  
Uses external 25 MHz clock or crystal input  
Power down pin turns off chip  
OE control tri-states outputs  
Spread and frequency selection via external pins  
Spread Bypass option available  
Industrial temperature range available  
NOTE: EOL for non-green parts to occur on 5/13/10  
per PDN U-09-01
