Power Supply Connector Pin Header, J15

Note that J17 comprises the signals needed for an I2S™ serial digital audio interface; the control interface

(I2C™ and RESET) signals are routed to J16. I2C is actually routed to both connectors; however, the

device is connected only to J16.

J15 provides connection to the common power bus for the TLV320AIC3104EVM. Power is supplied on the

pins listed in Table A-4.

The TLV320AIC3104EVM-PDK motherboard (the USB-MODEVM Interface board) supplies power to J15

of the TLV320AIC3104EVM. Power for the motherboard is supplied either through its USB connection or

via terminal blocks on that board.
