Intended use and compliance

The Ethernet FMC Max is an FPGA Mezzanine Card, a sub-assembly intended for incorporation into apparatus by professional integrators. It has no standalone function: it operates only when mounted on a compatible FMC carrier and driven by an FPGA design created by the integrator. Opsero has assessed the card's electromagnetic compatibility under the reference conditions described in its EMC integration notes and declares conformity on that basis. The integrator is responsible for the conformity of the apparatus into which the card is incorporated, including its enclosure, cabling, power supply and firmware. This is Class A equipment: in a residential environment it may cause radio interference, in which case the user may be required to take adequate measures.

Declarations and supporting information: Product compliance. EMC integration notes.

Frequently asked questions

What FPGA I/O voltages (VADJ) are supported by Ethernet FMC Max?

The Ethernet FMC Max was designed with level translators to enable it to support any VADJ voltage in the range of 1.2VDC to 2.5VDC.

Is the Ethernet FMC Max compatible with my FPGA board?

In general terms, the FPGA development board needs to have gigabit transceivers to use the Ethernet FMC Max, and those transceivers must be connected to the DP0-3 pins of the FMC connector. It also needs to be able to supply a VADJ voltage between 1.2VDC to 2.5VDC. 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 Ethernet FMC Max?

The typical application of the Ethernet FMC Max requires an IP for the MAC, such as the Xilinx Tri-mode Ethernet MAC (which is not free) or the OpenCores TEMAC (which is free). Some FPGAs have hard integrated TEMACs which generally don’t require a license to use. So the answer to this question depends on your FPGA and your choice of MAC.
