VITA 57.4:2018

This standard extends the VITA 57.1 FMC standard by specifying two new connectors that enable additional Gigabit Transceiver interfaces that run at up to 28Gbps. It also describes FMC+ IO modules which support this enhanced version of the FMC electro-mechanical standard. This is between the front panel IO, on the mezzanine module, and an FPGA processing device on the carrier card, which accepts the mezzanine module. Additional signals to support backplane reference clock and synchronization have been added. The VITA 57.4 specification is backwards compatible in that a VITA 57.4 carrier card can still support a VITA 57.1 FMC.
