- The board modifications shown above (switches, jumpers and resistor bridges) are specific to the **MAX96724** and **MAX96717** evaluation kits.
- If using a different SerDes evaluation board, refer to the table below for the correct resistors and consult the board's schematic for the equivalent switch and jumper settings.
