64-pin CK505 for Desktop Systems

1

Recommended Application:

CK505 clock, 64-pin Intel Yellow Cover part

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 < 500ps

•

+/- 100ppm frequency accuracy on CPU & SRC clocks

Features/Benefits:

•

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 SRC differential push-pull pair/two single-ended

outputs

1. FS

LA and FSLB are low-threshold inputs.Please see VIL_FS and VIH_FS specifications in

the Input/Supply/Common Output Parameters Table for correct values.

Also refer to the Test Clarification Table.

2. FS

LC is a three-level input. Please see the VIL_FS and VIH_FS

specifications in the Input/Supply/Common Output Parameters Table for correct values.
