Main features
  • Two QSFP+ ports
  • Up to 40 Gbps per port (IEEE 802.3ba)
  • 2-wire I2C communication interface and other low-speed electrical interface compliant to SFF 8436 and QSFP Multisource Agreement (MSA)
  • Programmable low jitter clock supports 0.16 to 350 MHz range with 1PPM step
  • Spread-spectrum clock support
  • 10 MHz, 0.5 PPM reference
  • FMC (ANSI/VITA57) Module
    (Note: module extends beyond FMC form-factor on the face plate. See mechanical requirements.)

FMC-QSFP+ provides dual SFP+ ports on a standard FMC module with programmable clock and support features. Fiber optic links to remote IO, such as Remote Radio Head applications, from host processing and FPGA cards support up to 40 Gbps bit rates.

The QSFP+ ports are compatible with SFF-xxxx transceivers, supporting both copper and fiber optic links. The four ports are fully independent on the module. QSFP+ monitoring and control signals are mapped to the FMC interface for detection, loss-of-signal, rate control and I2C control port.

A flexible reference clock for on the FMC-QSFP+ is fully programmable over the0.16 to 350 MHz range. The clock can be programmed for all common rates for standards such as OC-12, OBSAI, CPRI, GbE, sFPDP and SONET. The clock has jitter performance of less than 1 ps RMS max, allowing it to meet the most stringent requirements for these applications. An on-card 10MHz with 0.5 PPM stability is used as the PLL reference.

The FMC-QSFP+ is fully electrically compatible with FMC (ANSI/VITA 57) specifications for IO module. Mechanically, the module will fit FMC sites, but protrudes from the face plate for the SFPs. The module is compatible with FMC HPC sites (2 QSFP ports) or LPC (1 SFP port). The module consumes <500 mW exclusive of QSFP+ modules.

The FMC is provided with VHDL code illustrating the interfaces. Specific FPGA and platform support is provided for Innovative’s VPX- COP and PEX-COP FPGA cards.

Software libraries and examples for C++ host development are provided. Application examples demonstrating the module features are provided for Innovative Integration platforms in for Windows, Linux and VxWorks.
