A.2 Digital Interface Connectors, J4 and J5
The TLV320ADC3101EVM is designed to interface with multiple control platforms. Samtec part numbers
SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin, dual-row header/socket
combination at J4 and J5. These headers/sockets provide access to the digital control and serial data pins
of the device. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating
connector options. Table 6 summarizes the digital interface pinout for the TLV320ADC3101EVM.
