I found dufferential voltage provision for Zynq in SOM - ADRV2CRR-FMC case.
Could you teach me what purpose is these provision?
In another word, should these be aplied for original system/board which uses SOM?
ADRV2CRR-FMC P12-C4/5: 3V3_SNS_N/P -> SOM Zynq IO_L1N_AD15N/P_89
ADRV2CRR-FMC P12-C6/7: VDDA3P8_SNS_N/P -> SOM Zynq IO_L2N_AD14N/P_89
ADRV2CRR-FMC P12-C8/9: 5V0_SNS_N/P -> SOM Zynq IO_L3N_AD13N/P_89
ADRV2CRR-FMC P12-C10/11: VADJ_SNS_N/P -> SOM Zynq IO_L4N_AD12N/P_89
Moving this post to Linux software driver, as they are the team who designed the SOM modules.
These differential signals are sense voltages connected to ADC inputs of the Zynq Ultrascale on the SOM, in order to monitor these power supplies. All signals on the RF_SOM with '_AD' in their names are ADC inputs and you can use them.
Please note at this point we don't have software examples how to use them on this platform.
Thank you so much for this information.
Now I'm designing original board instead of ADRV2CRR-FMC for our system and boasically voltage minitoring isn't necessary in our system/application.
So I got I can skip making similar connection in our original board. :)
