This reference design is a scalable power supply designed to provide power to the Xilinx Artix-7: Spartan-7: and Zynq-7000 families of FPGA-based devices. The design receives power from a standard DC power supply and provides power to all rails of the Xilinx chipset and DDR memory through a well-defined Samtec socket-terminal strip connection.The design is scalable to support the most basic Spartan-7 FPGA device: a more complex Artix-7 FPGA with multi-Gigabit transceivers (MGTs): and up to the Zynq-7000 with a dual-core Arm Cortex-A9 processor. Due to its scalable design and the similarity of the Xilinx families of devices: this reference design is based on the TIDA-01480 power references design for the Xilinx Zynq UltraScale+ MPSoCs.
