Notes
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 Chipset supply voltages.
2.
The tolerances shown in Table 8-96 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 roll off of 3 dB/decade above 20 MHz.
3.
Includes CLK14, CLK48, LAN_CLK, and PCICLK.
