    Hello Mjain,

    Yes. Set the output as shown in figure 19. Output is referenced either 1.1V or 1.5V below VCCO.

    Note that this would be a non-standard LVDS termination in that the load is 50 ohms to ground on each output - not 100 ohms differential.

    The output requires a pull-down as it is not a true switched-current LVDS output.

    Are the input signals negative ECL?
