Where can i find the document about DDR LVDS design(XAPP705: Virtex-4 High-Speed Dual Data Rate LVDS Transceiver)? I can't find it on xilinx website.
Thanks!

You might also try XAPPs 707, 697, and 860, as well as XCELL 52. I found those useful. Looks like XAPP700 was also useful and is now superceded by XAPP860. It would be nice if the Application Notes page just referenced the new app note when someone is looking for the old one.

DDR and LVDS are separate mechanisms. DDR refers to how data are clocked out. LVDS refers to the electrical interface.

 

You can use DDR with any of the single-ended signaling standards.

 

You can use LVDS with SDR input and output.

Your answer isn't what I need.  I donot distinguish between DDR and LVDS. I need the reference design of XAPP705

The app note is fairly explicit and you should be able to infer the details from it. 

Sorry I didn't spoon feed you what you want.
