A small amount of external logic is required to connect the external FIFO ports in this way. Note that the bandwidth between the two SpW-10X devices is limited by the two external FIFO ports used to interconnect them. Each FIFO port can handle one SpaceWire packet at a time in each directionSpW-10X User ManualSpaceWire Router Figure 2-5 shows two SpW-10X router devices interconnected using two of the SpaceWire ports on each router. This leaves twelve SpaceWire ports for connection to other SpaceWire nodes. The External FIFO ports of each router are used to connect to user logic in an FPGA or to a processing deviceSpW-10X User Manual3.

It is important that the destination node is able to handle these casesSpW-10X User Manual9.
