How to connect external digital audio source to TLV320DAC3120EVM-U Evaluation Module

Other Parts Discussed in Thread: TLV320DAC3120EVM-U

Dear all,

I want to connect a DK-LM3S9B96 to a TLV320DAC3120EVM-U.

The Audio DAC EVM has all I2S signals available on testpoints:

TP3: MCLK for codec
TP4: I2S™ DIN to codec
TP5: I2S BCLK
TP6: I2S DOUT from codec
TP7: I2S WCLK

however, the TAS1020B on the EVM uses these singnas as well.

Whats the best way to disable the TAS1020B in order to playback the digital audio from the DK-LM3S9B96?

 

Thanks in advance,

Martin
