Note: Under worst-case operating conditions, the LVDS driver will withstand a disabled or unpowered receiver for an unlimited period of time

without being damaged. Similarly, when outputs are short-circuited to each other or to ground, the LVDS will not suffer permanent damage.

The LVDS driver supports hot insertion. Under a well-controlled environment, the LVDS I/O can drive backplane as well as cable.
