High speed differential to single ended

Hi,

What is the best way to convert a differential DVI signal to single ended for use in an FPGA?

I was thinking high speed op amp in unity gain, but unsure of this as I'm not an analog circuit buff.

I also need to take the output ports of the FPGA and convert them to differential signals. What is the best way to do this?

Thanks.

Isn't LVDS differential? Most FPGAs support it.

Hi,

I'm using a very low cost Xilinx Spartan FPGA, and it doesn't natively support differential I/O.

Thanks

There are LVDS receivers such as the Texasinstruments

The products you are looking for are differential line drivers / receivers / transceivers.

You probably don't want to use an op-amp or a normal comparator.
