LMH1982 & LMH1983 LVDS output

We have not characterized, nor do we guarantee the performance of the device during power-up and power-down.

Thanks

I got a reply from the design engineer:

The output common mode voltage is set by a current source and 200ohm resistor to gnd. Under normal condition and power down, it is impossible for the LVDS output to go above 2.5V. For powerup, it is unlikely to go above 2.5V. In a very low chance,  it is possible that the pre-emphasis circuit might generate a pulse that is tens of ps long while the main LVDS circuit is in highZ mode. In this case,  the output might go above 2.5V for a very short time at very light load.  If one can ramp up the 3.3V supply slowly and make sure it takes a few ns to raise from 2V to 2.5V  and let the pre-emphasis logic settle, then the LVDS cannot go above 2.5V.   Or just add diode to clamp the output voltage.

I assume that the customer concern is that he will damage the LVDS receive circuit, in which case I would interpret the answer from the customer as saying that this will not be a problem (if the only possibility is in Hi-Z mode, then there would not be enough energy in the output to cause damage.
