ICS9LPR501

1118E—08/08/07

Pin Configuration

Recommended Application:

CK505 compliant clock with fully integrated voltage regulator

Output Features:

•

2 - CPU differential low power push-pull pairs

•

10 - 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

•

Selectable between one SRC differential push-pull pair

and two single-ended outputs
