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. Refer to processor I/O Buffer Models for I/V characteristics.
5. The V
CC
referred to in these specifications is the instantaneous V
CC
.
6. Vol max of 0.450 V is guaranteed when driving into a test load of 50
Ω as indicated in Figure 2-7.
7. Leakage to V

value is defined for a platform that is forward compatible with future processors.
10.GTLREF value is defined for a platform that is forward compatible with future processors.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All outputs are open-drain.
3. The V
CC
referred to in these specifications refers to instantaneous V
CC
