Notes:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. V
IL
is defined as the maximum voltage level at a receiving agent that is interpreted as a logical low
value.
3. V
IH
is defined as the minimum voltage level at a receiving agent that is interpreted as a logical high
value.
4. V
IH
and V
OH
may experience excursions above V
CCP
. However, input signal drivers must comply with
the signal quality specifications.
5. This is the pull down driver resistance. Refer to processor I/O Buffer Models for I/V characteristics.

referred to in
these specifications is the instantaneous V

.
7. R

of the AGTL+ output driver. Measured at
0.31*V
CCP
. R
TT
is connected to V

on die. Refer to processor I/O buffer models for I/V
characteristics.
