VITA, the trade association for standard computing architectures serving critical and intelligent embedded computing systems markets, announces the ratification by ANSI and VITA of ANSI/VITA 57.4-2018 “FPGA Mezzanine Card Plus (FMC+) Standard”. This standard has completed the VITA and ANSI processes reaching full recognition under guidance of VITA. The FMC+ standard extends the Gigabit transceiver support specified in ANSI/VITA 57.1 by adding two new connectors that enable additional Gigabit transceivers running at higher data rates.
FMC+ adds an optional extension connector (the High Serial Pin Connector extension, or HSPCe) to boost pin-count by 80 positions, arranged in a 4 X 20 array. This brings the maximum multigigabit interfaces to 32 full duplex channels. Additionally, throughput per multigigabit interface has increased to 28 Gbps in each direction. This will allow for higher data rates and expanded bandwidth to all fit within the same form factor as FMC.
Additional signals to support backplane reference clock and synchronization have been added. The ANSI/VITA 57.4 standard defines functionality to maintain backward compatibility between new VITA 57.4 carrier cards and existing VITA 57.1 mezzanine modules.
