NOTES:
1. These power consumption characteristics are for all the valid input interfaces and cover the worst case input and output interface combinations.
2. The termnation resistors are excluded fromthese measurements.
3. If the differential input interface is used, the true input is held LOW and the complementary input is held HIGH.

is the nomnal 1.8V supply (1.8V ± 0.15V) of the part or source driving the input.
2. A nomnal 900mV timng measurement reference level is specified to allow constant, repeatable results in an automatic test equipment (ATE) environment.
3. The input signal edge rate of 2V/ns or greater is to be maintained in the 10% to 90% range of the input waveform

DDI
is the nomnal 1.8V supply (1.8V ± 0.15V) of the part or source driving the input. A nomnal 1.8V peak-to-peak input pulse level is specified to allow consistent, repeatable
results in an automatic test equipment (ATE) environment. Compliant devices must meet the V
DIF
(AC) specification under actual use conditions.
2. A nomnal 900mV crossing point level is specified to allow consistent, repeatable results in an automatic test equipment (ATE) environment. Compliant devices must meet 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 1.8V/ns or greater is to be maintained in the 20% to 80% range of the input waveform
