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...

Yes, 0.9V. Part of today's trend to invent your own standards rather use established ones. My data rate is not so high, and the LVDS amplitude is high enough, so I think it means I can just DC couple the inputs into the FPGA (using LVDS inputs at VCCIO of 2.5V). I guess there is one way to find out.

Thanks everyone.
