ICS9250-09

Frequency Timing Generator for PENTIUM II Systems

General Description

Features

Generates the following system clocks:

The ICS9250-09 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 ICS9211-01.

- 4CPUclocks(2.5V,100/133MHz)

- 8 PCI clocks, including 1 free-running (3.3V, 33MHz)

- 2CPU/2clocks(2.5V, 50/66MHz)

-3IOAPICclocks(2.5V,16.67MHz)

-4Fixedfrequency66MHzclocks(3.3V, 66MHz)

-2REFclocks(3.3V,14.318MHz)

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

ICS9250-09 employs a proprietary closed loop design, which

tightly controls the percentage of spreading over process

and temperature variations.

-1USBclock(3.3V,48MHz)

Efficient power management through PD#, CPU_STOP#

andPCI_STOP#.

0.5% typical down spread modulation on CPU, PCI,

IOAPIC, 3V66 and CPU/2 output clocks.

Usesexternal14.318MHzcrystal.

The CPU/2 clocks are inputs to the DRCG.
