Thanks, Tom. I appreciate your detailed feedback and suggestions!
Let me follow up to each of your points:
1. I am looking at using clock buffers and trying to minimize the propagation delay. Would zero delay buffers be acceptable to use?
2. May I use the same clock fanout buffers to process the MOSI? As for the MISO, I am considering using hex buffers with tri-state outputs (connecting all these outputs together and routing to the DSP).
3. I will focus on managing this delay and try to keep the trace lengths as matched as possible.
