[Figure 1-2, callout 30]
The AC701 board uses power regulators and PMBus compliant system controllers from
Texas Instruments to supply core and auxiliary voltages. The Texas Instruments Fusion
Digital Power graphical user interface is used to monitor the voltage and current levels of
the board power modules.
The AC701 board power distribution diagram is shown in Figure 1-43.
The pcb layout and power system design meets the recommended criteria described in the
UG483, 7 Series FPGAs PCB Design and Pin Planning Guide.
