Table 26. LVDS Operating Parameters
Note: Under worst-case operating condition, 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.
