We have connected another FPGA to the MIPI-CSI pins of the AGX Xavier board instead of the camera. That is, we are sending the camera data from another FPGA instead of the camera. But, the voltage level of the camera FPGA is 1.8V. And, the MIPI voltage level of the Xavier is 1.2V. Therefore, can we connect the 1.8V pins to the MIPIs of the 1.2 Volt Xavier module?

Hi, the signals output from your FPGA should obey the MIPI spec, which means 1.2V for LS.

If so, I have to use level shifter on that speed to combine them. Your answer was so useful. Thanks.
