RSDS
The LatticeECP/EC devices support differential RSDS standard. This standard is emulated using complementary
LVCMOS outputs in conjunction with a parallel resistor across the driver outputs. The RSDS input standard is sup-
ported by the LVDS differential input buffer. The scheme shown in Figure 3-4 is one possible solution for RSDS
standard implementation. Use LVDS25E mode with suggested resistors for RSDS operation. Resistor values in
Figure 3-4 are industry standard values for 1% resistors.
