Cyclone V LVDS & DDR3 on same bank

It's quite obvious, that the Arria V and Cyclone V IO topology is more or less identical. By the present documentation status, one would expect, that the VCCPD powered LVDS input buffers would work in a 1.5 V bank, but differential OCT won't.

As long as the support guy doesn't say which part of the Altera device manual is wrong and in which detail, I would consider the possibility that he just doesn't exactly. And the answer must not necessarily be well founded.

Of course lack of information can be a sufficient reason to stay away from the doubted solution.
