SPEC (Simple PCIE FMC Carrier)

The Simple PCIe FMC Carrier (SPEC) is an FMC carrier that can hold one FMC card and an SFP connector. This board is optimised for cost and will be usable with most of the FMC cards designed within the OHR project (e.g. ADC cards, Fine Delay). For boards needing more possibilities (e.g. programmable clock resources, fast SRAM, fast interconnect between carriers), the FMC PCIe Carrier or its VME counter part can be used.
