White Rabbit Oscillators on an FMC mezzanine

General

This project puts a set of White Rabit oscillators on an FMC card such that an FPGA on an evaluation board can be made White Rabbit timing aware.

Figure 1 is a picture of an assembled Rabbit FX PCB and Figure 2 shows a block diagram of the Rabbit FX.
