The FMCP HSPC (J28) VADJ pins and RFSoC U1 banks 66 and 67 VCCO pins are wired to the programmable rail VADJ_FMC. The VADJ_FMC rail is programmed to 1.80V by default.
Documentation describing PMBUS programming for the Infineon power controllers as well as PMIC and voltage regulator data sheets are available on the Infineon Integrated Circuits website.
Non-PMBus ADC and DAC voltage regulator data sheets can be viewed on the MPS website.
The PCB layout and power system design meet the recommended criteria described in the UltraScale Architecture PCB Design User Guide (UG583).
