The FMC PCIe Carrier is an FMC carrier that can hold one FMC card and an
SFP connector. On the PCIe side it has a 4-lane interface, while the FMC
mezzanine slot uses a low-pin count connector. This board is optimised
for cost and is usable with most of the FMC cards designed within the
OHR project (e.g. ADC cards, Fine Delay). The board is commercially
SPEC150 - with larger XC6SLX150T FPGA (PCI Device ID: 0x1A3) and
larger FLASH memory (M25P64 instead of M25P32).
Required for certain applications, e.g., when one needs White Rabbit support with the FMCADC100M ADC mezzanine card. Usage of the ADC with the White Rabbit Trigger Distribution project is such a case.
