Appendix A EVM Connector Descriptions
This appendix contains the connection details for each of the main connectors on the EVM.
A.1 Analog Interface Connectors
A.1.1 Analog Dual-Row Socket Details, J11 and J21
The TLV320DAC3203EVM has two analog dual-row sockets located at the bottom of the board. These
sockets provide support to the EVM and connect the analog ground plane of the EVM to the USB-
MODEVM analog ground. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety of
mating connector options. Table 3 summarizes the analog interface pinout for the TLV320DAC3203EVM.
