Electrical Specifications
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 V
IH
.
Note:
1. These signals are measured between V
IL
and V
IH
.
2. The signal edge rate must be met or the signal must transition monotonically to the asserted state.
