gigabit CMLtransceiver pin termination settings.

Hello everyone!

How should I set the terminations on pins tx / rx of a cyclone5GT, if I use the custom transceiver megafunction?

The tx of fpga line goes to an SFP module optical fiber (terminated 100 ohm diff AC coupled).

The rx of fpga line is connected to tx line (CML) of the SFP.

The megafunction automatically sets the terminations tx / rx?

It should be set to some other parameter (pre-emphasis etc ..)?

Regards, Luca
