Multiple LVDS inputs from Multiple sources- without DPA support

Hi i have a design working with Stratix II FPGA , it uses 44 LVDS inputs using DPA receiver for each , (eleven source , different distances, each sending 4 LVDS lines) now trying to find a ...

What's the data rate? Are the 11 sources all clocked off the same source clock? If they were completely independent and you absolutely needed DPA, then you would need 11 left/right PLLs, which I don't think any device has. I assume a single PLL/DPA can capture multiple inputs?

Can your sources send a clock signal, or is it just data with each?
