Cyclone V + ALTLVDS + Multi-channel ADC

Dear all, I am trying to fit a design in a Cyclone V FPGA (E series, A7, FBGA 484 pins). The FPGA receives 16 LVDS channels at 875 Mbps each. The data comes from a LTM9011-14 ADC from Linear Tec...

What's your ADC's sampling frequency?

I assume your speed is 100Mhz, and ADC's resolution is 14-bit. So your data rate will be 1400Mbps. LTM9011 support 2-Lane ouput mode, which means the maximum data speed can be decreased to 700Mbps. AS FvM said, only -6 grade device can support 875 Mbps. But i don't if -7 grade deivces can support above 700Mbps. You must check datasheet to confirm.
