You want to read Cyclone III Device Handbook, Chapter 7. high-speed differential interfaces in the cyclone iii device family

See e.g. Figure 7–3. LVDS Interface with External Resistor Network on the Top and Bottom I/O Banks

For other devices than Cyclone III, do a manual text search for "emulated LVDS".
