5641R PXIe lanes

[Jayash]

Does anybody know how many lanes (x1 x2 x4 x16) the 5641R requires?

Jayash,

I believe this is going to be more determined by the capabilies of your chassis and your controller than by the card itself at this point.   If I had to guess I would say the card had a maximum of x8 rev. 2 (but I'm not 100% sure and I can't find anything to confirm).

I do, however, know that our latest chassis (PXIe 1085) has x8 rev. 2 lanes.  Here are a couple dev zones that may help explain a bit more.

The 5641R uses a single lane (x1).

Robert,

Thanks for this.  Is there any documentation or anything that references this?

I can't find anywhere that it's called out specifically, but you can infer that it's a x1 connection from the "Data Transfer Rate" section of the spec document.
