General Description
Features
Generates the following system clocks:
- 6 CPU clocks ( 2.5V, 100/133MHz)
- 6 PCI clocks, including 1 free running(3.3V,
33MHz)
- 3 IOAPIC clocks (2.5V, 16.67MHz)
- 2 Fixed frequency 66MHz clocks(3.3V, 66MHz)
- 2 REF clocks(3.3V, 14.318MHz)
- 1 USB clock (3.3V, 48MHz)
Efficient power management through PD#,
CPU_STOP# and PCI_STOP#.
0.5% typical down spread modulation on CPU, PCI,
IOAPIC and 3V66 output clocks.
Uses external 14.318MHz crystal.

The ICS932S200 is a dual CPU clock generator for
serverworks HE-T, HE-SL-T, LE-T chipsets for P III type
processors in a Dual-CPU system. Single ended CPU
clocks provide faster than 1.5V/ns transition times by
parallel connection of 2 CPU pins to each processor.
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
ICS932S200
employs
a proprietary closed loop design, which tightly controls
the percentage of spreading over process and
temperature variations.
