General Description

ICS9LPRS525 is compliant Intel CK505 Yellow Cover specification. This clock synthesizer provides a single chip solution for Intel desktop chipsets. ICS9LPRS525 is driven with a 14.318MHz crystal. It also provides a tight ppm accuracy output for Serial ATA and PCI-Express support.

Features/Benefits:

• Supports spread spectrum modulation, 0 to -0.5 down spread

• Supports CPU clks up to 400MHz

• Uses external 14.318MHz crystal, external crystal load

caps are required for frequency tuning

Output Features:

• 2 - CPU differential low power push-pull pairs

• 7 - SRC differential push-pull pairs

• 1 - CPU/SRC selectable differential low power push-pull pair

• 1 - SRC/DOT selectable differential low power push-pull pair

• 1 - SRC/SE selectable differential push-pull pair/Single-ended outputs

• 5 - PCI, 33MHz

• 1 - USB, 48MHz

• 1 - REF, 14.318MHz

Recommended Application:

56-pin CK505 compatible clock, w/fully integrated Vreg and series

resistors on differential outputs
