PHY Ethernet to optics without external chip

Hello! Can anyone tell me, is it possible to create PHY ethernet on my Cyclone IV E using IP core or VHDL/Verilog? I also found "Custom PHY" IP core. Can I use it for all devices in family...

Thank's a lot for your reply.

Really, we are interesting in small Ethernet data rates, about 200 Mb/s. And we know that everyone use PHY in this case. What can you suggest? Can we do it without PHY?

Custom PHY megafunction is available only for transceiver FPGA's, but data rates starts from 620 Mb/s in that case. But if we want to work on lower speeds (about 200 Mb/s), is it necessary to place external PHY device on board or we can replace PHY chip by soft code or IP in FPGA (I mean create PHY using only resourses of FPGA).
