The HTG-Z922 provides access to large FPGA gate densities, wide range of I/O and expandable DDR4 memory for variety of different programmable applications. It is populated with the Xilinx Zynq Ultrascale+ ZU17-2 or ZU19-2 FPGA. Analog Devices power solution on this platform is fully validated to meet the requirements of Xilinx Zynq Ultrascale+ FPGAs to ensure a robust power delivery solution.

DC/DC μModule regulators are used on the HTG-Z922 to power Xilinx FPGA and/or SoC rails as well as other system rails. These regulators are highly integrated solutions with built in controller, power FETs, inductors, and capacitors that simplify layout and provide robust power delivery performance.

We provide supporting documentation including power schematics, layout, LTpowerPlanner and applicable LTpowerPlay configuration files to enable you to validate the power solution for your application seamlessly.

• Analog Devices has worked closely with Intel PSG to develop verified power solutions that optimize cost, size and efficiency in high performance applications.
• The validated power solutions include uModules power products that address time and space constraints while delivering high efficiency, reliability, and low noise.
• The actual power tree represents the best solution at time of design.
• A recommended power tree has also been included to present the ideal solution at time of Stratix 10 GX PCIe development kit release. An updated alternate version of the power tree represents the latest solutions available from Analog Devices. For many applications, an intermediate rail is not ideal, so recommendations an alternate power tree that allow for direct power conversion from 12V input is provided below.
