Electrical Specifications
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 will be interpreted as a logical low value.
3. V
IH is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
value.
4. V
IH and VOH may experience excursions above V
CC
. However, input signal drivers must comply with the
signal quality specifications in Section 3.
5. Refer to processor I/O Buffer Models for I/V characteristics.
6. The V
CC
referred to in these specifications is the instantaneous V
CC
.
7. Vol max of 0.450 Volts is guaranteed when driving into a test load of 50 Ω as indicated in Figure 6.
8. Leakage to V
SS
with pin held at V
CC
.
9. Leakage to V
CC
with pin held at 300 mV.
10.For a platform to be forward compatible with future portable processors it must be designed to support an
GTLREF value of 0.63*Vcc -2%(min) and 0.63*Vcc+2%(max). A compatible platform is one that is designed
for some level of compatibility with future portable processors.
11.For a platform to be forward compatible with future portable processors it must be designed to support an
Ron value of 8.4 Ω (min) and 13.2 Ω (max). A compatible platform is one that is designed for some level of
compatibility with future portable processors.
