TLV320AIC3204: AIC3204

Hi,

Please refer to the apps note below for clock configuration as I noticed you have an OSC connected to MCLK. Depending on your configuration slave/master there are certain relation of the clock with the host.

From the schematic, here are my comment:

• Recommend to place 0 Ohm on BCLK, WCLK, DIN and DOUT and also on the DMIC CLK and data
• For unused analog input IN3_L/R place a 0.47uF cap to GND
• Recommend to change C138/C139 to 47nF to form a LPF with Fc ~34KHz
• Please check if the connection is correct for the audio output, LINE out to an audio jack and HP output to an audio amp. Normally the HP is connected to the audio jack and LINE output is connected to the audio amp.
• Recommend to add 10uF cap to AVDD,DVDD and IOVDD along with the 0.1uF cap

Regards.

You need synchronization from the controller and the device.
