Systems
Functionality
Features/Benefits:
Supports tight ppm accuracy clocks for Serial-ATA and
PCI-Express
Supports spread spectrum modulation, 0 to -0.5%
down spread
Supports CPU clocks up to 400MHz
Uses external 14.318MHz crystal, external crystal load
caps are required for frequency tuning
Supports undriven differential CPU, SRC pair in PD#
for power management.
