3. Power Scheme
The CrossLink-NX Evaluation Board has most of its power supplied by onboard regulators powered by an external 12 V
power. Refer to Appendix A. CrossLink-NX Evaluation Board Schematics to see the details of these power supply
options. Figure 3.1 shows the high-level power supply architecture of the board. Table shows the voltage options
available for the various VCCIO supplies.
