Differential LVPECL
In Stratix IV devices, the LVPECL I/O standard is supported on input clock pins on
column and row I/O banks. LVPECL output operation is not supported in Stratix IV
devices. 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 the LVPECL input common-mode voltage.

external to the device.
Figure 6–32. LVPECL AC-Coupled Termination
Note to
(1) The LVPECL AC-coupled termination is applicable only when you use an Altera FPGA LVPECL transmitter.
DC-coupled LVPECL is supported if the LVPECL output common mode voltage is
within the Stratix IV LVPECL input buffer specification

Note to
(1) The LVPECL DC-coupled termination is applicable only when you use an Altera FPGA LVPECL transmitter.
