Lattice Semiconductor
LVDS Emulation
MachXO2 devices can support LVDS outputs via emulation (LVDS25E). The output is emulated using complemen-
tary LVCMOS outputs in conjunction with resistors across the driver outputs on all devices. The scheme shown in
Figure 3-1 is one possible solution for LVDS standard implementation. Resistor values in Figure 3-1 are industry
standard values for 1% resistors.
