General Description

ICS932S208 follows Intel CK409B Yellow Cover specification. This clock synthesizer provides a single chip solution for next generation P4 Intel processors and Intel chipsets. ICS932S208 is driven with a 14.318MHz crystal. It generates CPU outputs up to 200MHz. It also provides a tight ppm accuracy output for Serial ATA support.

Features/Benefits:

• Supports tight ppm accuracy clocks for Serial-ATA

• Supports spread spectrum modulation, 0 to -0.5 down spread and +/- 0.25 center spread

• Supports CPU clks up to 400MHz in test mode

• Uses external 14.318MHz crystal

Output Features:

• 4 - 0.7V current-mode differential CPU pairs

• 1 - 0.7V current-mode differential SRC pair

• 7 - PCI (33MHz)

• 3 - PCICLK_F, (33MHz) free-running

• 1 - USB, 48MHz

• 1 - DOT, 48MHz

• 2 - REF, 14.318MHz

• 4 - 3V66, 66.66MHz

• 1 - VCH/3V66, selectable 48MHz or 66MHz
