we need to input a continous stream of 32 LVDS data bits at 1.25gbps per pin into a Virtex-5. There is a clock provided for each byte (source synchronous).
There was a news item by Xilinx that says this is possible. But how many loops do I need to jump through to make it work?
- What speedgrade do we need?
- Is there a difference in timing between LXT, FXT and SXT for LVDS inputs?
- Are there any constraints regarding the placement of the pins?
Has anyone in this group done speeds like this before?
