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...

As gj_leeson said, you can run VCCIO at 2.5V and use LVDS inputs. The LVDS outputs from the 1.8V sensor will be compatible with the LVDS inputs in the Cyclone IV 2.5V bank. Check the data sheets (sensor and Cyclone IV) to verify this for yourself.
