    You can use the ALTPLL. However, it is not in the IP configuration that you specify that you want LVDS.

    In the 'Pin Planner' you will need to find your input clock signal and specify that it is an LVDS signal. Doing so will automatically add a second pin, the complimentary half of the signal you've selected, giving you CLKp & CLKn.

    Cheers,

    A LVDS input is represented by one interface signal, you select only the p pin of a differential pair in the pin planner or assignment editor and get the n pin selected automatically.
