Figure 18. Open-Circuit Fail Safe of the LVDS Receiver
It is only under these conditions that the output of the receiver is valid with less than a 100-mV differential input
voltage magnitude. The presence of the termination resistor, Rt, does not affect the fail-safe function as long as
it is connected as shown in the figure. Other termination circuits may allow a dc current to ground that could
defeat the pullup currents from the receiver and the fail-safe feature.
