Electrical Specifications
.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. VIL is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low value.
3. VIH 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 VCC referred to in these specifications is the instantaneous VCC.
6. Vol max of 0.450 V is guaranteed when driving into a test load of 50
7. Leakage to VSS with pin held at VCC.
8. Leakage to VCC with Pin held at 300 mV.
9. RON 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 VCC referred to in these specifications refers to instantaneous VCC.
4. This specification applies to the asynchronous GTL+ signal group.
5. The maximum output current is based on maximum current handling capability of the buffer and is not
