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 compliant carrier boards.
This FMC module is supported by four SFP/SFP+ ports and high-performance low-jitter Silicon Labs programmable clock (default = 156.25Mhz). The I2C interface between the oscillator and FPGA allows direct control of the SFP/SFP+ ports for wide range of different frequencies. The SFP/SFP+ ports are directly connected to four multi-gigabit serial transceivers of the FPGA carrier board.
