DATASHEET
56-pin CK505 for Intel Systems
ICS9LPRS525
Recommended Application:
56-pin CK505 compatible clock, w/fully integrated Vreg and series
resistors on differential outputs
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
Key Specifications:
• CPU outputs cycle-cycle jitter < 85ps
• SRC output cycle-cycle jitter < 125ps
• PCI outputs cycle-cycle jitter < 250ps
• +/- 100ppm frequency accuracy on all outputs
• SRC outputs meet PCIe Gen2 when sourced from PLL3
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
