A.2 Block A and Block B Digital Interface Connectors (J16 and J17)
Block A and Block B Digital Interface Connectors (J16 and J17)
The TLV320AIC34EVM 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 at J16 and J17. 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 A-3 summarizes the digital interface pinout for the
TLV320AIC34EVM.
