that pin high. The default is 000. Installing a shunt across J3 sets the address to 001.
3. Connect the 34-pin ribbon cable between header J800 on the TI Input USB board and header H1 on
the TPA5051EVM.
4. Connect the 16-pin ribbon cable between header J850 on the TI Input USB board and header H3 on
the TPA5051EVM.
5. Connect the USB cable from the USB jack on the PC to the J350 USB Interface on the TI Input USB
board.
6. For additional delay, another TPA5051EVM can be added in series using the 16-pin and 34-pin ribbon
cables.
7. Install shunts across J6 and J7. For stand alone evaluation, the shunts may be removed allowing for
separate LRCLK and BCLK signals for DATA1 and DATA2.
Note:
No pullup resistors are installed on the TPA5051EVM. Doing so interferes with the
initialization of the TI Input USB board in certain circumstances. However, the pads for the
pullup resistors, including SDA and SCL (R13 and R14, respectively), are available on the
EVM for populating if the EVM is to be used in a stand-alone fashion
