How to recombine LVDS data received from ADC in FPGA.

I am configuring an Analog to Digital Converter(ADC) reciently. I use AD9265. It works in LVDS mode, not CMOS mode. I learn something about LVDS from the datasheet of AD9265. It's my first time to ...

Before going for the full design I would simulate your FPGA code with a serialised ramp as an input and make sure you can decode it correctly. Then you can bring in the ADC.

Once you have got your simulation working, you can connect up the SPI of the ADC and write into register 0x0D. This according to the datasheet should make the ADC output one of the different test modes. Once you are decoding the test patterns correctly you know your circuit and FPGA code are working together.
