Cyclone IV GX Tranceivers

I am trying to interface a tranceiver link to a fiber link. The fiber link expects lvpecl. How exactly would I interface that. The tranceivers on the Cyclone IV transmit 1.5 PCML, and th...

A lot of transceiver interfaces are AC coupled, so then it is only the voltage swing that needs to be compatible.

If your fiber interface is being used to transmit encoded data, eg. 8/10B, then an AC coupled link to the FPGA PHY would be possible.

Take a closer look at the fiber transceiver documentation.

Cheers,
