What is the speed for the soft serde in Stratix IV EP4sGX530

I am using Stratix IV EP4sGX530( C3 speed) . 

My tool is Quatus II 10.0 

We know only Row I/Os support hard serde . 

so if I create LVDS mpdule in Column I/O , we must check " implement Deserializer circuitry in logic cell" , and create soft serde. 

Now question is , 

What is the speed for the soft serde in Stratix IV EP4sGX530? 

I wish it at least reach 625M data rate or higher?

The data rate is limited by the core clock, the involved DDR registers and the I/O. I would expect at least 800 Mbps. But without the hardware SERDES DPA functionality, you'll possibly have difficulties to get meaningful data from the serial input, considering delay skew.

Hi, 

 

How to implement soft-Serdes in core logic?
