    Features and Benefits

    • 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.
