10.5 Power

Management

Power Management capabilities of the MCH include the following:

•

ACPI 1.0b support

•

ACPI S0, S3, S4, S5, C0, C1, C2, C3, C4

•

Enhanced power management state transitions for increasing time the processor spends in
low power states

•

Graphics Adapter States: D0, D3.

•

PCI Express Link States: L0, L0s, L1, L2/L3 Ready, L3

•

PM_THRMTRIP# output

•

Conditional memory Self-Refresh during C2, C3, and C4 states

10.6 Clocking

The MCH has PLLs to provide the internal clocks.

•

Host PLL – This PLL generates the main core clocks in the host clock domain. The host PLL
is used to generate memory and internal graphics core clocks. It uses the Host clock
(HCLKIN) as a reference.

•

PCI Express PLL – This PLL generates all PCI Express related clocks, including the Direct
Media Interface that connects to the ICH6. This PLL uses the 100 MHz (GCLKIN) as a
reference.

Figure 10-2 illustrates the various clocks in the platform.
