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
