Warning!
No AC coupling capacitors are placed on the Mercury XU5 SoC module on the MGT lines - make sure
capacitors are mounted, if required, on the base board (close to the module pins), to prevent MGT lines
from being damaged.
2.11 Power
2.11.1 Power Generation Overview
The Mercury XU5 SoC module uses a 5 - 15 V DC power input for generating the on-board supply voltages
(0.72/0.85/0.9 V, 0.85/0.9 V, 0.9 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). Some of these voltages (1.8 V, 2.5 V, 3.3
V) are accessible on the module connector.
Table 13 describes the power supplies generated on the module.

Table 13: Generated Power Supplies
In the standard configuration, the PL core supply is 0.85 V. For product configurations, in which a speedgrade
-3E MPSoC device is equipped, an assembly option is available to switch the PL core operating voltage to
0.9 V. Similarly, in situations in which a speedgrade -2LE or -1LI device is used (custom configurations), an
assembly option is available to switch the PL core operating voltage to 0.72 V.
In the standard configuration, the PS core supply is 0.85 V. For custom configurations, in which a speedgrade
-3E MPSoC device is equipped, an assembly option is available to switch the PS core operating voltage to
0.9 V.
Operation at 0.9 V is not supported on modules revision 1 - please refer to the Mercury XU5 SoC Module
Known Issues and Changes document [7] for details.
Please refer to the Enclustra Module Pin Connection Guidelines for general rules on the power pins [11].
