I need to use a camera module along with De1-SoC development board. Camera requires 3.3V to work and it provides outputs with a 2.5V output pin.
I am trying to find what is the range of voltages that the FPGA will detect. I can not find that information easily anywhere in the specifications or any datasheets. This is the only official help I have found in the DE1-SoC User Manual. If the detection range for '0' is 0V-1.5V, and for '1' is 2.2V-5V I should be able to just plug the camera straight to the FPGA. Otherwise I would need to add additional voltage shifters.
If someone could point me to where I can find information regarding the official input detection characteristics I would be very grateful.
