2.1.1 USB-MODEVM Interface Board

The simple diagram of Figure 1 shows only the basic features of the USB-MODEVM Interface board.

Because the TLV320AIC3254EVM is a double-wide modular EVM, it is installed with connections to both

EVM positions, which connects the TLV320AIC3254 digital control interface to the I

C port realized using

the TAS1020B, as well as the TAS1020B digital audio interface.

In the factory configuration, the board is ready to be used with the USB-MODEVM. To view all the

functions and configuration options available on the USB-MODEVM board, see the USB-MODEVM

Interface Board schematic in Appendix G.
