Designing with mini-LVDS
Similar to RSDS, Cyclone II devices support the mini-LVDS output
standard using the LVDS I/O buffer types. For transmitters, the LVDS
output buffer can be used with the external resistor network shown in
Figure 11â10. The resistor values chosen should satisfy the equation on
page 11-8.
