Overview
Features & 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.
Circuit Function & Benefits
Intel’s Stratix® 10 GX FPGA Development Kit delivers a complete design environment that includes all hardware and software you need to start taking advantage of the performance and capabilities available in Stratix 10 GX FPGAs for your design needs.
Circuit Description
LTM4677 + 2x LTM4650’s is design in Intel’s Stratix 10 GX PCIE development kit as an ideal solution for core power. This is a scalable solution that can be sized appropriately depending on the Stratix 10 utilization. The LTM4677 PMBus Compliant uModule is coupled with multiple LTM4650’s to provide a scalable, high density solution.
LTM4700 x2 is an alternate recommended solution using the latest solution from ADI to provide power for the FPGA core rail.
Both solutions take advantage of the PMBus-Compliant I2C Serial to interface with the 14nm Stratix 10’s SmartVID to reduce the FPGA’s static and dynamic power consumption.
