The comment "running in Gbps" is a bit vague. Are you saying you want to capture an data stream that happens to be operating at Gbps data rate? If so, the answer is probably "No you cannot".
The Marvell PHY is designed for Gigabit data streams. The SGMII interface expects data encoded per whatever GbE encoding uses. It cannot be used to capture an arbitrary Gbps data stream.
Consider buying a Cyclone IV GX Starter kit and use the Gbps signals on its PCIe edge connector.
If you can describe what you are trying to do in more detail, members of this forum can provide ideas.

Let me clarify little more:
At first, I want to interface Ethernet MAC with Cyclone IVE by means of Marvell PHY (MII/RGMII Interface) . The data stream is still not fixed but it will be close to Gigabit.
It seems that Tripple Speed Ethernet MAC could fulfill my task. I am planning to use following Megacore function:
http://www.altera.com/literature/ug/ug_ethernet.pdf one more thing, do I need any license to use Megacore function (Tripple Speed Ethernet MAC) with QuartusII Web edition or its free like FIFO?
Is it worthy to proceed in this way or should I use some other alternative if any?
