It's the EP3C55F780C6.
You are right, I have been looking for LVDS receivers on the handbooks. Which turn into a big confusion to me.
I decided to place a resistor in the layout but will not be placed.
Let me search again on the documentation and I will turn back here.

If you cannot find the details, ask again, and I'll take a look.

I saw you are a radio astronomer professional. I am working on a very high speed low cost correlator for radio astronomy.

"High-speed" is subjective, how high in MHz? I'm currently testing Hittite's 20GHz ADC for use in an expensive correlator system :)
Are you considering a polyphase filter bank solution? If so, I've done some testing with the Altera FFT you may be interested in ...
