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. -- --------------------------------- --- -- - Posted with NewsLeecher v3.7 Final Web @ http://www.newsleecher.com/?usenet ------------------- ----- ---- -- -

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.
