8.2.2.3 Input Failsafe Biasing

External pull up and pull down resistors may be used to provide enough of an offset to enable an input failsafe under open-circuit conditions. This configuration ties the positive LVDS input pin to VDD through a pull up resistor and ties the negative LVDS input pin to GND by a pull down resistor. The pull up and pull down resistors should be in the 5kΩ to 15kΩ range to minimize loading and waveform distortion to the driver. Set the common-mode bias point to approximately 1.2V so that it is compatible with the internal circuitry. For more information, refer to application note AN-1194 Failsafe Biasing of LVDS Interfaces.
