Overview

Description #

The Ethernet FMC (FPGA Mezzanine Card) is an add-on/expansion board for FPGA and SoC based development boards. The mezzanine card has 4x Marvell 88E151x Gigabit Ethernet PHYs to provide 4 ports of gigabit Ethernet connectivity to the carrier development board.

Features #

• 4x Marvell 88E151x Gigabit Ethernet PHYs
• RGMII PHY interface
• Quad Ethernet RJ45 with magnetics
• FMC pinout conforms to VITA 57.1 FMC Standard
• Example designs with sources for several development boards
• Standalone and PetaLinux example designs

Variations #

To enable support for the majority of FPGA/SoC development boards on the market, the Ethernet FMC is available in two models and two voltage specifications.

The image above illustrates the differences between the Ethernet FMC and Robust Ethernet FMC. They are two physically different boards, however they use the same pinout on the FMC connector, allowing them to be used interchangably with the same software running on the carrier board. The main difference between the boards is that the Robust Ethernet FMC uses Ethernet magnetics that are external to the RJ45 connector. This allows the Robust Ethernet FMC to have a height profile that is physically compatible with more carrier boards than the Ethernet FMC. For more detail, see Mechanical Information.

Both the Ethernet FMC and the Robust Ethernet FMC are available in two different voltage ratings: 1.8VDC and 2.5VDC.

The table below lists the 4 variations and their part numbers.

To determine which Ethernet FMC is compatible with your development board, please refer to the list of compatible boards in the User Guide.
