Recommended Application:
Industrial temperature CK505 compatible clock for embedded
systems
Output Features:
• 2 - CPU differential low power push-pull pairs
• 9 - 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
• Integrated 33ohm series resistors on differential outputs,
Zo=50W
• Supports spread spectrum modulation, default is 0.5%
down spread
• Uses external 14.318MHz crystal, external crystal load
caps are required for frequency tuning
• Selectable between one SRC differential push-pull pair
and two single-ended outputs
• Meets PCIEX Gen2 specification on dedicated SRC
outputs. Muxed SRC outputs meet PCIEX Gen1
specification, except SRC1.
• Meets PCIEX <85ps cycle-tocycle jitter for SRC[11:1]
• Single-ended programmable slew rate control for RFI
