2.1.1 USB-MODEVM Interface Board
The diagram of Figure 1 shows only the basic features of the USB-MODEVM Interface board.
Because the PCM3070EVM is a double-wide modular EVM, it is installed with connections to both EVM
positions, which connects the PCM3070 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 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 F.
