I looking to use a AD9915 evaluation board in our lab setup. We have a Labview FPGA that has two 48 pin DIO outputs. We were hoping to use four AD9915 boards in our setup, so two per output. From what I understand the AD9915 uses 8 address lines and 8 data lines, plus a few additional lines. Will two boards be able to function off of 48 DIO lines? Is it possible for two boards to share address lines? Also, is the 1.8V power supply required if the USB interface is not being used? Is there Labview code already in place for parallel communication? Thanks.
