Circuit  
ICS9FG1901  
Systems, Inc.  
Frequency Generator for P4CPU, PCI Express& Fully Buffered DIMM Clocks  
Functionality at Power Up (PLL Mode)  
Recommended Application:  
CLK_IN (CPU FSB)

CLK_IN  
Features:  
Power up default is all outputs in 1:1 mode  
1. FS_A_410 is a low-threshold input. Please see the VIL_FS and  
IH_FS specifications in the Input/Supply/Common Output Parameters  
DIF_(16:0) can be “gear-shifted” from the input CPU

Spread spectrum compatible  
Supports output clock frequencies up to 400 MHz  
8 Selectable SMBus addresses

SMBus address determines PLL or Bypass mode  
VDDA controlled power down mode  
Functionality Note  
It is recommended that Byte 2, bit 6 be toggled from 1 to 0  
and back to 1, the first time VDDA is applied. This ensures  
proper initialization of the device.  
Key Specifications:  
DIF output cycle-to-cycle jitter < 50ps  
DIF (0:18) output-to-output skew < 225ps  
DIF (0:16) output-to-output skew < 100ps
