Note 1: “Absolute Maximum Ratings” are the ratings beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits.
Note 2: Typical parameters measured at V
specifications are not guaranteed.
Note 3: IN+ and IN− are generic names refer to one of the many pairs of complimentary inputs of the DS25MB100. OUT+ and OUT− are generic names refer to
one of the many pairs of the complimentary outputs of the DS25MB100. Differential input voltage V
defined as |OUT+–OUT−|.

Measured with a clock-like pattern at 2.5 Gbps,
between 20% and 80% of the differential output
voltage. Pre-emphasis disabled
Transition time is measured with fixture as shown in
Figure 5, adjusted to reflect the transition time at the
output pins
Measured at 50% differential voltage from input to
output
