BLVDS25
The LatticeECP3 devices support the BLVDS standard. This standard is emulated using complementary LVCMOS
outputs in conjunction with a parallel external resistor across the driver outputs. 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.
