PLL Related quary

Hi,

I want to know a PLL related quary..

Each PLL of ARRIA II GX FPGA has a fan out of 7.

Can those 7 outputs be independently configured?

Specifically, I mean can I use LVDS I/O standard on one PLL output

and LVTTL on another output line of same PLL?

    Yes, you can.

    The I/O standard will be determined by choosing the right I/O buffer, no by the PLL or any other internal component.
