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
