Description

NOTE: This is a new product. Our team is still working on the documentation and reference design. If you have specific questions about this product that are not covered on this page, please contact us.

The MCIO PCIe Host FMC is an FPGA Mezzanine Card designed to bring high-speed MCIO connectivity to FPGA and adaptive SoC development platforms. It supports cabled PCIe Gen4 connections with up to 8 lanes or dual 4-lane (2x4) configurations, enabling direct interface with high-performance devices such as NVMe SSDs, GPUs, and custom accelerators. The board integrates two TI DS320PR810 PCIe redrivers to compensate for signal loss, ensuring reliable signal integrity over MCIO cables and adapters. For more detailed information on the MCIO PCIe Host FMC, including datasheets, schematics and example designs, please visit the product website.

Frequently asked questions

What are the supported PCIe link speeds?

This product supports up to PCIe Gen4 (16Gbps per lane) on all 8 lanes.

What FPGA I/O voltages (VADJ) are supported by MCIO PCIe Host FMC?

The MCIO PCIe Host FMC was designed with level translators to enable it to support any VADJ voltage in the range of 1.2VDC to 3.3VDC.

Is the MCIO PCIe Host FMC compatible with my FPGA board?

In general terms, the FPGA development board needs to have gigabit transceivers to use the MCIO PCIe Host FMC, and those transceivers must be connected to the DP0-7 pins of the FMC connector. It also needs to be able to supply a VADJ voltage between 1.2VDC to 3.3VDC. Please visit the product website for a list of compatible FPGA boards and detailed compatibility requirements.

Do I need any purchased IP to use the MCIO PCIe Host FMC?

The minimum requirement for interfacing an FPGA with an U.2 NVMe SSD is a PCIe IP core, however, these days many FPGA development boards have an FPGA with integrated PCIe block. If your FPGA board has an integrated PCIe block, and it can be routed to the gigabit transceivers of the FMC connector without timing issues, you will not need any purchased IP to use the MCIO PCIe Host FMC. The reference designs rely on the Xilinx PCIe integrated block and they allow a U.2 NVMe SSD to be accessed in PetaLinux. In that use case, the NVMe protocol is handled by the operating system, or more specifically by the embedded microprocessor. If you have an application where the NVMe protocol must be handled in the FPGA fabric, you may require purchased IP.
