+/- 300ppm frequency accuracy on CPU & SRC clocks
Programmable Timing Control Hub for Next Gen P4 processor
Functionality
Features/Benefits:
Supports tight ppm accuracy clocks for Serial-ATA.
Supports spread spectrum modulation, 0 to -0.5%
down spread.
Supports CPU clks up to 400MHz in test mode.
Uses external 14.318MHz crystal, external crystal load
caps are required for frequency tuning.
Supports undriven differential CPU, SRC pair in PD#
and CPU_STOP# for power management.
