Frequency Timing Generator for Pentium II Systems  
General Description  
The ICS9250-10 is a single chip clock for Intel Pentium IIꢀ  
Features  
•
Generates the following system clocks:  
-3CPU(2ꢀ5V)66ꢀ6/100MHz(upto133MHzthrough  
It provides all necessary clock signals for such a systemꢀ  
I2C selection)  
- 9SDRAM(3ꢀ3V)upto133MHz  
-8PCI(3ꢀ3V)@33ꢀ3MHz  
-2IOAPIC(2ꢀ5V)@16ꢀ67or33ꢀ3MHz  
- 2Hublinkclocks(3ꢀ3V)@66ꢀ6MHz  
- 2 USB (3ꢀ3V) @ 48 MHz ( Non spread spectrum)  
- 1REF(3ꢀ3V)@14ꢀ318MHz  
Spread spectrum may be enabled through I2C programmingꢀ  
Spread spectrum typically reduces EMI by 8dB to 10 dBꢀ  
This simplifies EMI qualification without resorting to board  
design iterations or costly shieldingꢀ The ICS9250-10  
employs a proprietary closed loop design, which tightly  
controls the percentage of spreading over process and  
temperature variationsꢀ  
•
Supports spread spectrum modulation ,  
down spread 0 to -0ꢀ5%
