MLVDS
The LatticeECP2/M devices support the differential MLVDS standard. This standard is emulated using complemen-
tary LVCMOS outputs in conjunction with a parallel resistor across the driver outputs. The MLVDS input standard is
supported by the LVDS differential input buffer. The scheme shown in Figure 3-5 is one possible solution for
MLVDS standard implementation. Resistor values in Figure 3-5 are industry standard values for 1% resistors.
