Lvds_io

Hi, I am working on a project and a part from it is using LVDS_IO with the buffer as a comparator to compare 2-input signals. My question is how we send the analog signal to the FPGA even though i...

u do need LVDS_IO to implement the ADC. I am not sure about altera DE1 but most of the FPGAs have LVDS_IO and some of them have built_in ADCs.

thanks icd.

but i got that even without LVDS-IO we can implement the sigma delta ADC on FPGA with both analog comparator and RC network out of the FPGA. and do the rest of the circuit inside the FPGA.
