RSDS
The LatticeXP2 devices support differential RSDS standard. This standard is emulated using complementary LVC-
MOS 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. Resistor values in Figure 3-4 are industry standard values for 1% resistors.
