Hi all, I have a question.

I have a design using lvds interface. Currently it is implemented with ALTDDR_in IP but no ALTLVDS. The input of ddr_in is mapped to a pin labeled with LVDS in pin assignment.

Now I see something about the ALTLVDS IP, and it can be used with the same function as ddr_in. I wonder which way is more efficient, in the power point of view.

Thanks~~~~~~~~~~:)

Another question. Does LVDS has a high impedance output state besides '0' and '1'. Because it consumes a lot static power......

Thanks~~~~~
