PHY Layer FPGA

With all the applications for SERDES and 1000BASE products, I would think that there might be a device which I could program that will perform the 100BASE-TX and/or 100BASE-FX function that I am look...

Some of the FPGA devices offer the ability to use fewer byte lanes and also make available an intermediate exit place for the extracted data. I need clock extraction and logic to do the optional scrambler and I do not know if it exists in the world of programmable logic devices.

I am running into an obsolescence problem with my PHY devices which like to run an MII interface using 5B symbol modes. If I could replace them with programmable logic, that would solve the problem.
