Chapter 3: Board Component Descriptions
The ZCU104 evaluation board uses both PMBus compliant POL controllers and no-PMBus
regulators from Infineon Technologies [Ref 22] to supply the core and auxiliary voltages
listed in Table 3-31 . The schematic page references are to 0381794.
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 Table 3-2,
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) [Ref 4] .
