Per the MicroZed Carrier card user guide and design guide: The VCCIO banks that receive power from the carrier can be powered independently or tied together depending on your needs. We wanted to use them independently but looking at the Carrier schematic the VCCIO pins on JX1 and JX2 are the same net so I don't see how these can be used independently at the same time but maybe I'm missing something?
I also wanted to clear up the logic levels of the MicroZed using the Carrier Card - the JX1/JX2 interface can be either 1.8V, 2.5V, or 3.3V (depending on jumper used on carrier card) - these pins can be used single-ended (say 3.3LVCMOS - so we'd use 3.3VCCIO jumper) or differentially (2.5 LVDS - so we'd use 2.5V jumper)
Thank you
