BLVDS
The MachXO family supports the BLVDS standard through emulation. The output is emulated using complemen-
tary LVCMOS outputs in conjunction with a parallel external resistor across the driver outputs. The input standard is
supported by the LVDS differential input buffer on certain devices. BLVDS is intended for use when multi-drop and
bi-directional multi-point differential signaling is required. The scheme shown in Figure 3-2 is one possible solution
for bi-directional multi-point differential signals.
