Connector supports increased multi-Gbit interfaces and data rates
Compliant to the ANSI/VITA 57.4-2016 standard, the FMC+ connectors support the expanded interface and faster speeds of the latest FMC+ applications, says Samtec.
The new ANSI/VITA 57.4-2016 standard extends the capabilities of ANSI/VITA 57.1-2010 in support of the increased number and data rates of multi-Gbit interfaces found in advanced FPGA architectures. Highlights include increases multi-Gbit interfaces from 10 to 32, increases interface data rates from 10 to 28Gbit/s
The ANSI/VITA 57.4-2016 standard defines two mated connected pairs that embody the new FMC+ electromechanical interface. A new high serial pin count (HSPC) connector contains 560 pins arranged in a 14×40 array. The connector supports up to 24 multi-Gbit interfaces. A second, optional high serial pin count extension (HSPCe) connector contains 80 pins in a 4×20 array. The HSPCe connector supports up to eight additional multi-Gbit interfaces.
The combination of HSPC and HSPCe connectors enable support of up to 32 multi-Gbit interfaces. With each interface running up to 28Gbit/s, the ANSI/VITA 57.4-2016 specifications provides maximum system level throughput of 896Gbit/s via the 32 channels.
ANSI/VITA 57.4-2016 also supports backwards compatibility for ANSI/VITA 57.1-2010 FMC modules. The HSPC connector uses a customised polarisation system enabling proper mating with FMC HPC and LPC connectors. HSPC connectors provide additional columns compared to legacy FMC connectors. This design approach enables additional signals without compromising board profiles or mechanics.
The application-specific versions of SEARAY adopted by VITA 57.4 support the growing FMC+ ecosystem in applications as diverse as high-speed ADCs and DACs, next generation RF connectivity, high-speed serial memory and high-density fibre optics, says the company.
