Hi, I have to acquire 9 couples of differential signals inside my Spartan3 fpga. How should I handle them? Should i use IBUFDS (with I and IB as true and inverted inputs, while O as my "decoded" output)? Is it 2.5V (with the inverted being -2.5V) the maximum allowed differential input voltage with XC3S200 FT256? Thanks, Marco
