LVPECL
The MachXO family supports the differential LVPECL standard through emulation. This output standard is emu-
lated using complementary LVCMOS outputs in conjunction with a parallel resistor across the driver outputs on all
the devices. The LVPECL input standard is supported by the LVDS differential input buffer on certain devices. The
scheme shown in Figure 3-3 is one possible solution for point-to-point signals.
