NOTES:
1. The 732mV peak-to-peak input pulse level is specified to allow consistent, repeatable results in an automatic test equipment (ATE) environment. This device meets the V
DIF
(AC)
specification under actual use conditions.
2. A 1082mV crossing point level is specified to allow consistent, repeatable results in an automatic test equipment (ATE) environment. This device meets the V
X
specification
under actual use conditions.
3. In all cases, input waveformtimng is marked at the differential cross-point of the input signals.
4. The input signal edge rate of 1V/ns or greater is to be maintained in the 20% to 80% range of the input waveform

to a new state.
4. V
