ICS9250-11  
Frequency Timing Generator for PENTIUM II/III™ Systems  
General Description  
Features  
The ICS9250-11 is a main clock synthesizer chip for Pentium  
II based systems using Rambus Interface DRAMs. This chip  
provides all the clocks required for such a system when used  
with a Direct Rambus Clock Generator (DRCG) chip such as  
the ICS9212-01, 02, 03 and a PCI buffer 9112-17.  
•
Generates the following system clocks:  
- 6 - CPU Clocks 100/133MHz (2.5V).  
- 2 - CPU/2 output for synchronous memory  
reference (2.5V).  
- 4 - fixed frequency Clocks @ 66.6MHz (3.3V).  
- 2 - fixed frequency Clocks @ 33.3MHz (3.3V).  
- 6 - IOAPIC Clocks @ ¼ of CPUCLK or 16.667MHz,  
synchronous to CPU Clock (2.5V)  
- 1 - 48MHz Clock (3.3V)  
Spread Spectrum may be enabled by driving the SPREAD#  
pin active. Spread spectrum typically reduces system EMI by  
8dB to 10dB. This simplifies EMI qualification without  
resorting to board design iterations or costly shielding. The  
ICS9250-11 employs a proprietary closed loop design, which  
tightly controls the percentage of spreading over process and  
temperature variations.  
- 2 - REF Clocks @ 14.31818MHz  
•
•
0.5% typical down spread modulation on CPU, PCI,  
IOAPIC, 3V66 and CPU/2 output clocks.  
The CPU/2 clocks are inputs to the DRCG.  
Uses external 14.318MHz crystal.
