Setting an output pin to LVDS is not part of the megafunction. You can use
the assignment editor to accomplish what you want.
Writing your own serailizer usually takes a fairly good understanding of the
hardware, setup/hold times, and jitter.

Hi,
does anybody know how to switch of the LVDS output pins of a Cyclone
II?
I use the "alt_lvds" megafunction but there are no inputs to this
megafuction to enable or disable the LVDS output pins.
I thought about writing my own serializer as a workaround but I have
no idea how this is done. But it should be possible by using the
double data rate IOs and some shift registers.
Thanks.
