8.3.6 Cross-Point Switch

Each group of two adjacent channels in the DS250DF810 has a 2×2 cross-point that may be enabled to implement a 2-to-1 mux, a 1-to-2 fanout, or an A-to-B/B-to-A lane cross. A cross-point exists between the following channel pairs:

  • Channel 0 and Channel 1
  • Channel 2 and Channel 3
  • Channel 4 and Channel 5
  • Channel 6 and Channel 7
