1.8V LVDS inputs

Hello, I am using a Cyclone IV EP4CE15 FPGA and I need to accept 1.8V LVDS inputs from an image sensor. (100R termination, 150mV voltage swing, 0.9V common mode voltage). I am unsure how to d...

I understand what you are saying. As long as the amplitude of the LVDS signal are the same then the Cyclone LVDS receivers will operate. But as the common mode voltages are different (0.9V against 1.25V) would I not have to AC couple the LVDS inputs?
