-The AD-FMComms5 (AD9361) assumes a VDD_INTERFACE voltage between 1.71V and 2.625V (1.8 to 2.5 +/- 5%), so on your FPGA carrier board, you should ensure that V<sub>ADJ</sub> is between these levels. Setting things to 3.3V will damage the part.+The [[ADI>AD-FMCOMMS5-EBZ]] (AD9361) assumes a VDD_INTERFACE voltage between 1.71V and 2.625V (1.8 to 2.5 +/- 5%), so on your FPGA carrier board, you should ensure that V<sub>ADJ</sub> is between these levels.

 ===== Phase Synchronization ===== ===== Phase Synchronization =====
  
-Traces between baluns and SMAs are not phase matched on REV-A and REV-B which can cause phase misalignment with the libad9361-iio ad9361_fmcomms5_phase_sync solution. This is corrected on REV-C. Therefore, phase alignment performance can vary over frequency. The RF switches on REV-A/B are also not designed to work above 900 MHz. Higher frequency switches are available on REV-C.+Traces between baluns and SMAs are not phase-matched on REV-A and REV-B which can cause phase misalignment with the libad9361-iio ad9361_fmcomms5_phase_sync solution.
