6.3 USB-MODEVM Interface Board
The simple diagram shown in Figure 1 shows only the basic features of the USB-MODEVM Interface
board. The board is built around a TAS1020B streaming audio USB controller with an 8051-based core.
The board features two positions for modular EVMs, or one double-wide serial modular EVM may be
installed.
Since the TLV320AIC11xxEVM is a double-wide modular EVM, it is installed with connections to both
EVM positions, which connects the TLV320AIC11xx digital control interface to the I
2
C port realized using
the TAS1020B, as well as the TAS1020B digital audio interface.
In the factory configuration, the board is ready to use with the TLV320AIC11xxEVM. To view all the
functions and configuration options available on the USB-MODEVM board, see the USB-MODEVM
Interface Board schematic in Appendix B.
6.4 Program Description
After the TLV320AIC11xxEVM software installation (described in Section 6.2) is complete, evaluation and
development with the TLV320AIC11xx can begin.
