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
