Low Power Clock for Intel Atom^®-Based Systems
DATASHEET
ICS9LPRS436C
Recommended Application:
NM10 Express Chipset + N450/D410/D510 Atom^® CPUs
Output Features:
• 2 - 0.8V push-pull differential CPU pairs
• 2 - 0.8V push-pull differential PCIEX pairs
• 1 - 0.8V push-pull differential SATA75 pair
• 1 - 0.8V push-pull differential DOT96 pair
• 1 - 0.8V push-pull differential CPU/PCIEX selectable pair
• 1 - PCI (33MHz)
• 1 - PCICLK_F, (33MHz) free-running
• 1 - USB, 48MHz
• 1 - 12/48MHz
• 1 - 25MHz
• 1 - REF, 14.318MHz
• 1 - 12.288MHz
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 all clocks
Features/Benefits:
• VDDSUSP allows 25MHz to run in S-states
• Supports programmable spread percentage
• Uses external 25MHz crystal, external crystal load caps
are required for frequency tuning
• PEREQ# pins to support PCIEX/SATA power
management.
• Low power differential clock outputs (No 50Ω resistor to
GND needed)
• Integrated 33Ω series resistor on all differential outputs.
