Samtec releases FMC+ connector set

Dec. 10, 2016

New Albany, IN. Samtec, a privately held global manufacturer of a line of electronic interconnect solutions, has announced the release of a high-speed board-to-board connector family compliant to the ANSI/VITA 57.4-2016 standard. Samtec’s family of FMC+ connectors helps support the expanded interface and faster speeds of the latest FMC+ applications.

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-gigabit interfaces found in advanced FPGA architectures. The new standard increases multigigabit interfaces from 10 to 32, increases multigigabit interface data rates from 10 Gb/s to 28 Gb/s, and maintains backwards compatibility with VITA 57.1 FMC modules.

The new 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 x 40 array. The HSPC connector supports up to 24 multigigabit interfaces. A second, optional High Serial Pin Count extension (HSPCe) connector contains 80 pins in a 4 x 20 array. The HSPCe connector supports up to eight additional multigigabit interfaces.

The combination of HSPC and HSPCe connectors enable support of up to 32 multigigabit interfaces. With each multigigabit interface running up to 28 Gb/s, the ANSI/VITA 57.4-2016 specifications provide maximum system level throughput of 896 Gb/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 customized polarization 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.

“Samtec’s SEARAY High-Density Open Pin Field Arrays set the standard for high-speed mezzanine applications,” said Matt Burns, Technical Marketing Manager at Samtec. “The application specific product 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 fiber optics.”
