Vita 57 provides a mechanical standard for I/O mezzanine modules. This standard introduces a methodology that shall allow the front panel IO of IEEE 1101 form factor cards to be configured via mezzanine boards. Vita 57 modules have fixed locations for serial/parallel IOs, clocks, Jtag signals, VCC, and GND. HiTech Global's Vita 57 modules can be plugged into any Vita 57 based boards.

The FMC standard specifies Samtec’s SEARAY™ connector set. The VITA 57 SEAM/SEAF Series system provides 400 I/Os in a 40 x 10 configuration or 160 I/Os in a selectively loaded 40 x 10 configuration, in 8.5mm and 10mm stack heights.

The FMC SFP+ is a FPGA Mezzanine Connector (FMC) daughter card with two SFP+ connectors, two 10Gbps physical layer transceiver which provide full PCS, PMA, and XGXS sub-layer functionality, on board clock, and FMC connector for interfacing (XAUI) with any Vita57 compliant carrier card including the following boards:

Xilinx Virtex-5 TXT
Xilinx Virtex-6 PCIe
Xilinx Virtex-6 ML605
Altera Stratix 4GX
