Datasheet
Recommended Application:
Key Specifications:
CK505 compliant clock with fully integrated voltage
regulator and Internal series resistor on differential outputs,
PCIe Gen 1 compliant
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
Pin Configuration
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
Features/Benefits:
Does not require external pass transistor for voltage
regulator
Integrated 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
One differential push-pull pair selectable between
SRC and two single-ended outputs
