AD9083EBZ buzzing noise when powered

Thread Summary

The user encountered a buzzing noise when connecting the AD9083EBZ to a custom FMC board. The issue was resolved by bypassing a circuit interfering with the PG_C2M signal, which was causing the voltage monitor to malfunction. Next, the user will troubleshoot SPI communication issues.

We're evaluating the AD8093 for a new design, so we attached the AD9083EBZ to our custom board (i.o.w. not the zcu102). This board so far worked fine with any FMC add-on we've used.

When I plug the AD9083EBZ into the FMC and power-on the system, it yields a worrying buzzing noise, as if some DC convertor is being maltreated.

The FPGA pins at this stage are all tri-stated, there's no logic driving them (yet).

I'll try to borrow a zcu102 board to see if the evaluation board is just DOA. Any comments from your side?
