Intel Xeon Datasheet

Intel® Xeon™ Processor with 800 MHz System Bus
Datasheet 29
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. The V
TT
represented in these specifications refers to instantaneous V
TT
.
3. V
IL
is defined as the voltage range at a receiving agent that will be interpreted as a logical low value.
4. V
IH
is defined as the voltage range at a receiving agent that will be interpreted as a logical high value.
5. V
IH
and V
OH
may experience excursions above V
TT
.
6. Refer to Table 6 to determine which signals include additional on-die termination resistance (R
L
).
7. Leakage to V
SS
with pin held at V
TT
.
8. Leakage to V
TT
with pin held at 300 mV.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All outputs are open drain.
3. V
HYS
represents the amount of hysteresis, nominally centered about 0.5 * V
TT
for all PWRGOOD and TAP
inputs.
4. The V
TT
represented in these specifications refers to instantaneous V
TT
.
5. The maximum output current is based on maximum current handling capability of the buffer and is not
specified into the test load.
