Clocks  
ICS9FG107  
Description  
Features/Benefits  
ICS9FG107 is a Frequency Timing Generator that provides 7  
differential output pairs that are compliant to the Intel CK409/CK410  
specification. It provides support for PCI-Express, next generation I/  
O, and SATA. The part synthesizes several output frequencies from  
either a 14.31818 Mhz crystal or a 25 MHz crystal. The device can  
also be driven by a reference input clock instead of a crystal. It  
provides outputs with cycle-to-cycle jitter of less than 85 ps and  
output-to-output skew of less than 85 ps.  
Generates common CPU/PCI Express frequencies from  
14.318 MHz or 25 MHz  
Crystal or reference input  
7 - 0.7V current-mode differential output pairs  
3 - 33MHz PCI outputs  
1 - REFOUT  
Supports Serial-ATA at 100 MHz  
Two spread spectrum modes: 0 to -0.5 downspread and  
+/-0.25% centerspread  
ICS9FG107 also provides a copy of the reference clock and 333  
MHz PCI output clocks. Frequency selection can be accomplished  
via strap pins or SMBus control.  
Unused inputs may be disabled in either driven or Hi-Z  
state for power management.  
Key Specifications  
Output cycle-to-cycle jitter for DIF outputs < 50 ps (<85ps  
@ 266 MHz)  
Output to output skew for DIF outputs < 85 ps  
+/-300 ppm frequency accuracy on output clocks  
48-pin SSOP/TSSOP package  
Available in RoHS compliant packaging
