4. Overshoot is defined as the absolute value of the maximum voltage.
5. Undershoot is defined as the absolute value of the minimum voltage.
6. Ringback Margin is defined as the absolute voltage difference between the maximum Rising Edge Ringback
and the maximum Falling Edge Ringback.
7. Threshold Region is defined as a region entered around the crossing point voltage in which the differential
receiver switches. It includes input threshold hysteresis.
8. The crossing point must meet the absolute and relative crossing point specifications simultaneously.
9. VHavg can be measured directly using "Vtop" on Agilent* scopes and "High" on Tektronix* scopes.
10.
V
CROSS is defined as the total variation of all crossing voltages as defined in note 2.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies and cache sizes.
2. VIH is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
value.
3. VIL is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low value.
4. VIH and VON may experience excursions above VCC. However, input signal drivers must comply with the
signal quality specifications in Chapter 3.0.
5. Refer to the Intel Xeon Processor with 512 KB L2 Cache Signal Integrity Models for I/V characteristics.
6. The VCC referred to in these specifications refers to instantaneous VCC.
7. VOL_MAX of 0.450 V is guaranteed when driving into a test load as indicated in Figure 5, with RTT enabled.
8. Leakage to VCC with pin held at 300 mV.
9. Leakage to VSS with pin held at VCC.

NOTES:.
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies and cache sizes.
2. All outputs are open drain
