     9The FMC standard dedicates pins for 10 multi-gigabit transceivers (MGTs), labeled DP![0:9] in the standard. The Mango FMC-RF-2X245 module connects 4 transceivers to SATA connectors.

     11'''Important''': the FMC-RF-2X245 module MGT interfaces are not intended for connections to SATA devices (like hard drives). While it may be possible to implement a standard SATA host in the FPGA and connect it to an SATA target via the FMC-RF-2X245 module, this is '''not''' something we have tested. These interfaces are intended for connections between FPGA kits, each equipped with FMC-RF-2X245 modules.

     15The FMC-RF-2X245 module has four SATA connectors. Each connector is tied to a single 4 data signals on the FMC header (Tx +/-, Rx +/-).
     16
     17Two of the SATA connectors are wired as hosts; the other two are wired as targets. This allows two FMC-RF-2X245 modules to be connected via a standard (non-crossover) SATA cable.
     18
     19All Tx and Rx data lines for all 4 connectors are AC-coupled on the FMC-RF-2X245 module with 0.1µF capacitors.
