LVDS25E
The top and bottom sides of LatticeECP3 devices support LVDS outputs via emulated complementary LVCMOS
outputs in conjunction with a parallel resistor across the driver outputs. The scheme shown in Figure 3-1 is one
possible solution for point-to-point signals.

LVCMOS33D
All I/O banks support emulated differential I/O using the LVCMOS33D I/O type. This option, along with the external
resistor network, provides the system designer the flexibility to place differential outputs on an I/O bank with 3.3V
V
4mA, 8mA, 16mA or 20mA. Follow the LVCMOS33 specifications for the DC characteristics of the LVCMOS33D.
