The FMCP HSPC (J28) V
ADJ
pins and RFSoC U1 banks 66 and 67 V
CCO
pins are wired to the
programmable rail VADJ_FMC. The VADJ_FMC rail is programmed to 1.80V by default.
Documentaon describing PMBUS programming for the Inneon power controllers as well as
PMIC and voltage regulator data sheets are available on the Inneon 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).
RECOMMENDED:
To ensure reliable operaon, Xilinx recommends running the report_power
command in the Vivado tools for designs targeng this board. The reported rail current requirements must
not exceed the values listed in the following table.
