Quad SFP28 FMC

Description

The Quad SFP28 FMC is an FPGA Mezzanine Card designed to connect up to four SFP28 modules to your FPGA or MPSoC development board. It includes a jitter-attenuating clock multiplier, the Skyworks Si5328, which generates two precision clocks programmable from 8kHz to 808MHz. Additionally, the card supports the use of a recovered clock for Synchronous Ethernet applications. For more detailed information on the Quad SFP28 FMC, including datasheets, schematics and example designs, please visit the product website.

• 4x SFP28 slots compatible with SFP, SFP+ and SFP28 modules
• Jitter-attenuating clock multiplier (Skyworks Si5328) with support for recovered clock and SyncE applications
• HPC FMC compliant with VITA 57.1
• Supports a wide range of I/O voltages (VADJ): 1.2V-3.3V
• Reference designs for multiple FPGA and MPSoC development boards
• Straightforward tech support

Intended use and compliance

The Quad SFP28 FMC 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 Quad SFP28 FMC?

The Quad SFP28 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 Quad SFP28 FMC compatible with my FPGA board?

In general terms, the FPGA development board needs to have gigabit transceivers to use the Quad SFP28 FMC, 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 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 Quad SFP28 FMC?

Not necessarily. It depends on your FPGA device. We provide example designs for the Quad SFP28 FMC that use free IP, as well as designs that use paid IP:

• MRMAC (free): Uses the Integrated 100G Multirate Ethernet MAC (MRMAC), a hard block in AMD Versal devices, configured as four 10G or 25G channels. The MRMAC requires a license key from AMD, but it is free of charge.
• 10G/25G Ethernet Subsystem (paid): Uses the AMD 10G/25G Ethernet Subsystem, which is a paid IP core, and supports Zynq UltraScale+ and Versal devices. You can evaluate it for free with an evaluation license from AMD.

On Versal devices you can use the Quad SFP28 FMC without any paid IP. On devices without a hardened multirate MAC, you will need a soft MAC such as the 10G/25G Ethernet Subsystem, or any other MAC of your choice.
