Programmable Timing Control Hub™ for Desktop P4™ 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 clks 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.
