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 BCLK{0/1}_DN is equal to the falling
edge of BCLK{0/1}_DP.
3. V
Havg
is the statistical average of the VH measured by the oscilloscope.
4. The crossing point must meet the absolute and relative crossing point specifications simultaneously.
5. V
Havg
can be measured directly using "Vtop" on Agilent* and "High" on Tektronix oscilloscopes.
6. V
CROSS
is defined as the total variation of all crossing voltages as defined in Note 3.
7. The rising edge of BCLK{0/1}_DN is equal to the falling edge of BCLK{0/1}_DP.
8. For Vin between 0 and Vih.
9. Specifications can be validated at the pin.
