RSDS
The MachXO family supports the differential RSDS standard. The output standard is emulated using complemen-
tary LVCMOS outputs in conjunction with a parallel resistor across the driver outputs on all the devices. The RSDS
input standard is supported by the LVDS differential input buffer on certain devices. 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.
