NOTES:
1.
Parameter applies to the PWRGOOD signal only.
2.
V
and V
only apply when BCLK, BCLK# and PICCLK are stopped. PICCLK should be stopped in the
low state. See Table 30 and Table 31 for DC levels when BCLK and BCLK# are stopped.
3.
Measured at 9 mA.
4.
V
should be created from a stable 1.5V supply using a voltage divider. It must track the voltage supply
to maintain noise immunity. The same 1.5V supply should be used to power the chipset CMOS I/O buffers that
drive these signals.
5.
(0

V
IHx,max
).
6.
Specified as the minimum amount of current that the output buffer must be able to sink. However, V
OL,max
cannot
be guaranteed if this specification is exceeded.
7.
Parameter applies to VTTPWRGD signal only.
8.
Parameter applies to GHI# signal only.
9.
Applies to non-AGTL signals except BCLK, PWRGOOD, PICCLK, BSEL[1:0], VID[4:0].
10. ±5% DC tolerance. CLKREF must be generated from the same 2.5V supply used to generate the BCLK signal.
AC Tolerance must be less than -40dB at 1 MHz. The CLKREF DC spec only applies to platforms supporting
single-ended clocking.
11. Applies to all TAP and CMOS signals (not to APIC signals).
12. Applies to PICD[1:0].
