AFCK may be overkill.

How about this: * we reduce the number of channels per AMC to 4 DACs + 4 ADCs * we can therefore use a smaller FPGA. Communication lanes to the master board are relatively cheap if we put them on IOSERDES. * the power density and cooling requirements are also reduced. * for the RF daughter cards, we use a custom form factor that can use at least 2/3 of the AMC front panel * connectors between the DSP card and the RF daughter card are 2mm header and 8x SMP * the rest of the AMC front panel used for (optional, runtime selectable) clock input and some TTLs.
