General Description

ICS9LPRS535 is compliant to the Intel CK505 Yellow Cover specification. This clock synthesizer provides a single chip solution for Intel desktop chipsets. ICS9LPRS535 is driven with a 14.318MHz crystal. It also provides a tight ppm accuracy output for Serial ATA and PCI-Express support.

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

Output Features:

• Integrated Series Resistors on differential outputs

• 2 - CPU differential push-pull pairs

• 4 - SRC differential push-pull pairs

• 1 - CPU/SRC selectable differential push-pull pair

• 1 - SRC/DOT selectable differential push-pull pair

• 1- SRC/Stop_Inputs selectable differential push-pull pair

• 1 - 25MHz SE1 output for Wake-on-Lan applications

• 3 - PCI, 33MHz

• 1 - USB, 48MHz

• 1 - REF, 14.31818MHz

Recommended Application:

48-pin Low Cost CK505 w/fully integrated VREG and series resistors on differential outputs
