Figure 6. PPCMB and TAS5766MRMTEVM
The green LED on the bottom left corner of the PPC window indicates the initialization of TAS5766M is
valid.
The PPCMB is initialized with the USB audio (USB-AudioEVM) selected. Streaming audio from the USB
host is routed to the TAS5766M.
If an optical input is used, click on the OPT IN symbol on the PPC software, the I2S is then routed with
this signal. Likewise, with a COAX/SPDIF input using the COAX IN symbol. If an analog input is used,
click on the LINE IN symbol on the PPC software, the ADC (PCM3168A) is the source of I2S data.
