Arria 10 GX FPGA Development Kit FMC Transceiver Channel Performance

Hello,

What is the channel loss / maximum performance supported through the FMC interface? The user guide says it is compliance to VITA 57.1 which is 25+ Gb/s and the Samtec SEAF connectors are similarly rated to 28+. Whereas for the Aria 10 GX part in the eval board the transceivers are rated at a maximum of 15 Gb/s @ 1.03v for chip to chip and 12.5 for back-plane w/o DFE.

Thanks
