Serial supports for Alveo cards, e.g., U280

Hi everyone,

I wonder if Alveo cards targeting date centers supports serial links as Virtex. I took a look at the device list that support FMC connectivity cards, but did not found Alveo cards in it (https://www.xilinx.com/products/boards-and-kits/fmc-cards.html). Does that mean Alveo U280 can only be used individually?

Thanks,

Wenqi

None of the Alveo boards have FMC or FMC+ connectors.  The Alveo boards only bring out transceivers for PCIe and Ethernet (QSFP28), all other sites are disabled in the device files and not routed on the board.  So, the U280 has only 24 transceiver channels available - 16 for PCIe on the edge connector, and 8 for the QSFP28 modules, four per module.  All other transceiver sites are locked out and marked as 'unavailable' in Vivado.
