VADJ_FMC Power Rail

The ZCU102 evaluation board implements the ANSI/VITA 57.1 section 5.5.1 IPMI support
functionality. The power control of the V
controller. This rail powers both the FMC HPC0 (J5) and the FMC HPC1 (J4) V
as the XCZU9EG HP banks 65, 66 and 67. The valid values of the V
and 1.8V.
At power on, the system controller detects if an FMC module is connected to each interface:
• If no cards are attached to the FMC ports, the V
• When one FMC card is attached, its IIC EEPROM is read to find a V
supported by both the ZCU102 board and the FMC module, within the available
choices of 1.8V, 1.5V, 1.2V, and 0.0V.
• When two FMC cards are attached with differing V
the lowest value compatible with the ZCU102 board and the FMC modules, within the
available choices of 1.8V, 1.5V, 1.2V, and 0.0V.
• If no valid information is found in an FMC card IIC EEPROM, the V
0.0V.
