Power Supply Architecture
While the board needs multiple supply voltages, all these voltages are generated
from the 12V power of the AMC connector.
All supply voltages can be monitored over IPMI. In the special case of
programming the MMC controller the first time, the 3.3V management power can be
delivered by the SPI programmer on the SPI download connector, in this way being
possible to program the MMC outside the crate without additional power supply.
Power domains are listed below:
