Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. Crossing voltage is defined as the instantaneous voltage value when the rising edge of BCLK0 equals the
falling edge of BCLK1.
3. VHavg is the statistical average of the VH measured by the oscilloscope.
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.
