3.4 Codesign Schematic Example

Figure 2-5, Figure 3-9, and Figure 3-10 show schematic diagrams for an example codesign which can be used with DS2x0DF810 retimers, DS280BR8x0 redrivers, and DS280MB810 redriver with crosspoint. A few component replacements are necessary to use each device with this codesign.
