I always do what FvM suggested. I've asked that the LVDS block just get created with an external PLL by default, and then the user can edit it from there if they want to. Hopefully that gets done someday, because the setup is not intuitive.

Remember that if you generate one with an internal PLL, create an .sdc that has "derive_pll_clocks" in it. This should add multicycles from the fabric to the LVDS block that you can just copy into your design.
