  1. Hello, I am considering to buy a FPGA board from Digilent. I need to interface it with a chip, designed by me, which has some analog mixed signal circuitry and can have maximum voltage of 900mV. First, I am not sure as what is the output voltage level from the fpga board. If I understand correctly, it should be 3.3V in Nexys4 DDR Artix-7. Secondly, how should I regulate the output voltage from the fpga board and make it 900mV to be compatible with my chip ? In this regard, do we something in-built in the board itself ? Hoping for a prompt response from your side. Thanks and regards, Saurabh ([email protected])
