Recommended Application:

Low Power CK505 Compliant Main Clock

Output Features:

• 2 - 0.8V push-pull differential CPU pairs

• 7 - 0.8V push-pull differential PCIEX pairs

• 1 - 0.8V push-pull differential SATA pair

• 1 - 0.8V push-pull differential CPU/PCIEX selectable pair

• 1 - 0.8V push-pull differential 27MHz/LCDCLK/PCIEX

selectable pair

• 4 - PCI (33MHz)

• 2 - PCICLK_F, (33MHz) free-running

• 1 - USB, 48MHz

• 1 - DOT96/PCIEX selectable pair

• 2 - REF, 14.318MHz

Key Specifications:

• CPU outputs cycle-cycle jitter < 85ps

• PCIEX outputs cycle-cycle jitter < 125ps

• SATA outputs cycle-cycle jitter < 125ps

• PCI outputs cycle-cycle jitter < 500ps

• +/- 100ppm frequency accuracy on CPU, PCIEX and

SATA clocks

• +/- 100ppm frequency accuracy on USB clocks

Features/Benefits:

• Supports tight ppm accuracy clocks for Serial-ATA and

PCIEX

• Supports programmable spread percentage and

frequency

• Uses external 14.318MHz crystal, external crystal load

caps are required for frequency tuning

• PEREQ# pins to support PCIEX power management.

• Low power differential clock outputs (No 50Ω resistor

to GND needed)

• iAMT support
