68 / 386 page  3-16 DC and Switching Characteristics Lattice Semiconductor LatticeECP2/M Family Data Sheet 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. Figure 3-5. MLVDS (Multipoint Low Voltage Differential Signaling) Table 3-6. MLVDS DC Conditions 1 For further information about LVPECL, RSDS, MLVDS, BLVDS and other differential interfaces please see the list of additional technical information at the end of this data sheet.
