    Hi Zach, 

    I am assuming you are requesting for the LMK1D1204. It should be similar to to LMK1D1208.

    Below is a layout for how it was done on TI EVM. If you are just using DC coupled LVDS then I would say 100 ohm between the P and N is perfectly fine to avoid too many stubs on the transmission lines.

    Let me know if you have any further questions.

    Best,
