LVPECL
The MachXO2 family supports the differential LVPECL standard through emulation. This output standard is emu-
lated using complementary LVCMOS outputs in conjunction with resistors across the driver outputs on all the
devices. The LVPECL input standard is supported by the LVDS differential input buffer. The scheme shown in Dif-
ferential LVPECL is one possible solution for point-to-point signals.

cal documentation at the end of the data sheet.
