General Description

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.

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.
