FMC carriers typically have FMC site(s) on them, a large user FPGA and either links to an external host or an onboard host. The carriers that are plug in boards, the PEX6-COP plugs into a desktop PC PCIe slot. The SBC-K7 has a COMexpress host CPU and can be supplied on its own or in a case (ePC-K7) or a smaller version can be supplied as the mini-K7. The mini-K7 can also be supplied rugged. Sites are either HPC (high pin count) or LPC (low pin count).

FMC modules are based around the VITA 57 specification and typically contain ADC’s, DAC’s, SFP ports as well as the necessary clock generators and functionality. They are designed to connect to a host with a FMC site. The signal pins of the site are connected direct to a FPGA for a flexible interface to the components. ISI LLC make a few carriers and these come with logic for interfacing to Innovative modules.

We support logic development when the module and carrier are both Innovative Integration Inc products. The carriers come complete with VHDL logic frameworks and software examples to enable streaming of data from Adc(s) to host processor and streaming of data from host processor to Dac(s).
The FMC-10GE fits on the LPC site of the ePC-K7 and comes with Intel drivers to run on the host processor.
The interfacing of FMC modules to FMC requires knowledge of the interface details and chipset used on the FMC module. Below is a table of information to assist. The notes are very basic and the datasheet should be consulted for further details.
