Differential LVPECL
Arria II GX devices support the LVPECL I/O standard on input clock pins only.
LVPECL output operation is not supported. LVDS input buffers are used to support
LVPECL input operation. AC-coupling is required when the LVPECL common mode
voltage of the output buffer is higher than Arria II GX LVPECL input common mode
voltage.
