The FMC LPC (J5) VADJ pins are wired to the programmable rail VADJ_FMC. The VADJ_FMC
rail is programmed to 1.80V by default. The valid values of the VADJ_FMC rail are 1.2V, 1.5V,
and 1.8V. The VADJ_FMC rail also powers the XCZU7EV HP banks 67 and 68 (see
page 23).
Documentation describing PMBus programming for the Infineon Technologies PMIC
flexible power management unit power controllers is available at the Infineon Technologies
website [Ref 22]. The PCB layout and power system design meets the recommended criteria
described in the UltraScale Architecture PCB Design User Guide (UG583)
