LVDS Emulation
MachXO devices can support LVDS outputs via emulation (LVDS25E), in addition to the LVDS support that is avail-
able on-chip on certain devices. The output is emulated using complementary LVCMOS outputs in conjunction with
resistors across the driver outputs on all devices. The scheme shown in Figure 3-1 is one possible solution for
LVDS standard implementation. Resistor values in Figure 3-1 are industry standard values for 1% resistors.
Figure 3-1. LVDS Using External Resistors (LVDS25E)
The LVDS differential input buffers are available on certain devices in the MachXO family.
