The TLV320AIC11xxEVM is designed to easily 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. 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 3 summarizes the digital interface pinout for the TLV320AIC11xxEVM.
