Connecting MxFE JESD204B in Loopback/No Processor

Hello there,

I was interested in seeing if we could naively connect integrated transceivers together via JESD240B, but without having a processor in between them. Is there any reason I would need a FPGA/Processor in between? Specific use case is having AD9081 or AD9082 connected "back to back" on the PCB. I don't see anything immediately wrong with this in hardware/electrical reasons, but I am not sure if i there is something to the JESD PHY that may be only on the processor side.
