David,
I received an additional question related to the following E2E thread.
https://e2e.ti.com/support/rf-microwave-group/rf-microwave/f/rf-microwave-forum/1236873/afe7906-question-about-connection-between-2x-afe7906-with-a-xilinx-fpga/4690915#4690915
Can unused 4 lanes at each AFE7906 be left floating (unconnected anywhere)?
Best regards,
K.Hirano
