4.1.2 Optional EVM Connections

Figure 5-3 shows optional connections to the power, clock, and VCM. These connections are not required for initial setup of the EVM but can be helpful to configure the EVM more closely to the end application configuration. Review the schematic and hardware sections of this document to understand how these connections are used.
