Part Number: TLV320AIC3204 Other Parts Discussed in Thread: TLV320AIC33
Tool/software:
We use multiple CODECs (TLV320AIC3204) connected to a host. To have control over the MCLK quality we have an external MCLK source and make one CODEC Master, the…

Hi,TI
Now we are debugging…
Hello,
Regarding the MSP430 and TLV320AIC33, please see the app notes below which discuss interfacing to MSP430 via I2C or I2S.

The datasheet for both chips tlv320aic3104 and tlv320aic33 and slaa454 says that they can detect the difference between mono and stereo headsets, but there is a difference in the description of the registers:
In R13 tlv320aic3104:
Headset Type Detection…
Hi,
1. A series capacitor is not necessary. You can optionally include a coupling capacitor reduce out of band noise.
2. MICDETECT pin is primarily used for headset detection. Explained in detail with multiple configurations here: Headset Detection…
Hi Lev,
The connection seems fine as is, the customer is setting the common mode of the headphone driver to GND just as the sleeve (pin 1) of the the audio jack is connected to GND.
Additionally, this application note covers different headphone output…
Hello Ryo,
Apologies for the delayed response. We were on holiday 4/10.
I have attached links to some App Notes that provide information on interfacing with TDM.
Using TLV320AIC3x Digital Audio Data Serial Interface With Time-Division Multiplexing…
Hello Tadahiko-san,
You can connect DOUT_A and DOUT_B to the same bus and use TDM mode in the device. This will allow the customer to slot the data out. The processor would have to be set up to recognize one slot of data is from DOUT_A and the other…
Hello Matthew,
You mentioned you are using one of your boards, to be clear this is not a TI EVM correct?
if it is one of your boards, can you PM me the codec portion of the Schematic? I'd just like to see what you have implemented.
We do have an…
Part Number: TLV320AIC3111 Other Parts Discussed in Thread: TLV320AIC33 , TLV320AIC3101 , Hello,
I'm having problems with headset detection on TLC320AIC3111 platform. I am not using the EVM; the device is integrated on a custom board running Linux,…
