Cyclone IV as transceiver using SMA

thanks a lot for the answer Cs1400.

The development kit i have bought is the Cyclone IV GX Transceiver Starter KIt, in which are embebed SMA connector for making transmission through them, being able of seeing the eye diagram later on in the osciloscope.

The problem i have is that i dont know how to make the code. If you see the page 2-22 of the manual is talking about the SMA connector, but is just saying some changes you need to make in the fpga for using them.

i dont know if i need to use some protocol or just create a PRBS and a clock code.

i have checked in the device handbook and i have found the pins in which the transmitter & the receiver are connected to

( SMA_TX_P -> ENETR_TX_P -> C2

SMA_TX_N -> ENETR_TX_N -> C1

SMA_RX_P -> ENETR_RX_P -> E2

SMA_RX_N -> ENETR_RX_N -> E1 )

but i also dont know how to use this signals.

I want to make a variable rate transmission, which is going to depend on the lenght of the PRBS data. (but i want to start with a transmission of 2,5 Gbit/s)

Thanks you so much.
