Lattice Semiconductor
MLVDS
The LatticeXP2 devices support the differential MLVDS standard. This standard is emulated using complementary
LVCMOS outputs in conjunction with a parallel resistor across the driver outputs. The MLVDS input standard is sup-
ported 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.
