Lattice Semiconductor
BLVDS
The MachXO2 family supports the BLVDS standard through emulation. The output is emulated using complemen-
tary LVCMOS outputs in conjunction with resistors across the driver outputs. The input standard is supported by
the LVDS differential input buffer. BLVDS is intended for use when multi-drop and bi-directional multi-point differen-
tial signaling is required. The scheme shown in Figure 3-2 is one possible solution for bi-directional multi-point dif-
ferential signals.
