+'''VADJ note''': the FMC VADJ net is tied to the digital interface power supplies of multiple circuits on the FMC-RF-2X245 module. These interfaces are all specified over the range 1.8-2.5v. However, we have only tested this module on the WARP v3 kit, which ties VADJ to 2.5v.

-The FMC-RF-2X245 module uses I/O from the LA, HA and HB banks. However FMC signals HB20(n/p) and HB21(n/p) are unused, for compatibility with the WARP v3 HPC slot.
