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 scheme shown in Figure 3-3
is one possible solution for RSDS standard implementation. Use LVDS25E mode with suggested resistors for
RSDS operation. Resistor values in Figure 3-3 are industry standard values for 1% resistors.

5V Tolerant Input Buffer
The input buffers of the LatticeECP/EC family of devices can support 5V signals by using a PCI Clamp and an
external series resistor as shown in Figure 3-4.
