NOTES:
1. For all noise components ≤20 MHz, the sum of the DC voltage and the AC noise component must be within the
specified DC min/max operating range on the ICH7 supply voltages.
2. The tolerances shown in Table 23-8 are inclusive of all noise from DC up to 20 MHz. In testing, the voltage
rails should be measured with a bandwidth limited oscilloscope that has a rolloff of 3 dB/decade above 20 MHz.
3. Includes CLK14, CLK48, LAN_CLK, and PCICLK.
