Recommended Application:
CK505 compliant clock with fully integrated voltage
regulator, PCIe Gen 1 compliant
Output Features:
• 2 - CPU differential low power push-pull pairs
• 7 - SRC differential low power push-pull pairs
• 1 - CPU/SRC selectable differential low power push-pull pair
• 1 - SRC/DOT selectable differential low power push-pull pair
• 5 - PCI, 33MHz
• 1 - PCI_F, 33MHz free running
• 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 CPU & SRC
clocks
Features/Benefits:
• Does not require external pass transistor for voltage
regulator
• Supports spread spectrum modulation, default is 0.5%
down spread
• Uses external 14.318MHz crystal, external crystal
load caps are required for frequency tuning
• One differential push-pull pair selectable between
SRC and two single-ended outputs
