TLV320AIC3204: Works half the time

Part Number: TLV320AIC3204
Other Parts Discussed in Thread: CC8520,

Hello,

I'm a bit confused with this device. I use it with a CC8520 mcu.

In DAC mode, it works all the time.

In ADC mode, it works around 1 time on 2.

When it works, it's great without cut off.

When it doesn't work, I have some snippets of sound.

I have to turn off then on the device one time or two and it's ok.

I'm wondering if it's a clock problem, desync signal or something like that, but in DAC it's always ok.

If someone can find why it has this behavior?

Thank you

I found something,
I was at 48kHz sampling rate, but if I put 32kHz I have more sound than cut off when it doesn't work.
I think it's a sync issue, MCLK is generated by mcu, maybe I have to use the PLL of the codec?
Can someone help me with that?

An other thing,
Sometime, sound is mute and then it's powering slowly. Maybe it's a problem of initialization time, I tried changing MICPGA startup delay and Reference charging time but no difference..

Hi, Frederic,

Could you provide your register configuration, please? Additionally, could you provide the MCLK frequency that you are using? If you are using the device in slave mode, could you provide the BCLK and WCLK frequencies? Finally, what sampling rate will you be using?

Thank you.

Best regards,
Luis Fernando Rodríguez S.

MCLK : 12.288 MHz
BCLK : 3.072 MHz
WCLK : 48 kHz
Sampling rate : 48 kHz

I checked with a scope, it is ok. One time I put the probe, sound started to cut off, but frequencies stay the same.
Maybe a power issue? I use LDO
Maybe I should try with internal PLL but I don't know how.

thank you

edit: no problem in DAC mode

Hi, Frederic,

I reviewed your register configuration and it seems that the PGA and the ADC are not being enabled. Could you verify if Page 1 / Registers 59-60 and Page 0 / Registers 81-82 are configured according to your requirements?

The PLL and LDO seem to be enabled properly.

I would only recommend to verify the power supplies levels. Ensure that all the power supplies are stable and in the recommended operating conditions.

Best regards,
Luis Fernando Rodríguez S.

Hello,

Thank you for your answer.

ADC was enabled in an other sequence.
I put it in first sequence and add what was missing :

w 30 12 81 # Power up the NADC divider with value 1
w 30 13 82 # Power up the MADC divider with value 2
w 30 14 80 # Program OSR for ADC to 128
w 30 51 C0 # Power up ADC channels
w 30 52 00 # Un-mute
# DIGITAL INTERFACE
w 30 1B 20 # I2S, 24-bit, BCLK and WCLK are inputs
# PROCESSING BLOCK USAGE
w 30 3D 01 # Select ADC processing block PRB_R1
# ANALOG POWER SUPPLY
w 30 00 01 # Select register page 1
w 30 01 08 # Disable internal crude AVDD before powering up the internal AVDD LDO
w 30 02 01 # Enable internal analog LDO, analog blocks powered
w 30 0A 00 # Common mode set to 0.9V
w 30 3b 00 # pga enabled
w 30 3c 00 # pga enabled

But no difference, sometime it work great and other it cut off.

I'm powering with a dc-dc converter at 3.3V and it looks stable.

Do you have an other advice?

thank you

edit : it's linked to the powering up : when it's ok it's ok for ever, I powering down then up and it can be always good or always bad randomly

Hi, Frederic,

When the internal LDO is used, we recommend to turn it on before configure the rest of registers.

I would recommend to start with a hardware and software reset respecting the described delays in the Application Reference Guide. Then, power up the ALDO, disable the weak AVDD to DVDD connection and enable the analog blocks.

The registers configuration sequence is necessary to get a proper initialization of the device. I would recommend to check the wake up mode in the document below for more details:

Hello,

Thank you for your answer,

I changed registers configuration regarding the wake up mode, but there is something I couldn't do :
1) power up the ALDO
2) disable the weak AVDD to DVDD connection
3) enable the analog blocks

I only could do :
1) power up the ALDO and enable the analog blocks
2) disable the weak AVDD to DVDD connection

I have still the same issue..

Hello, Frederic,

Could you provide the AIC3204 schematic portion? I tested this configuration on our evaluation board and it worked correctly.

Additionally, have you followed the recommended power up sequence?

HI Louis,

I used CC85XX headset reference design 1_3_SCHEMATIC.pdf as reference :

I checked with evaluation board's schematic and chip's documentation's schematic but didn't see big difference.

For the power up sequence, regarding I use LDOIN, there is nothing to do, I use the same power source.

Is there any hardware difference between DAC mode and ADC mode? I can't see that.

Thank you for your concern

Hi,

It's a little better, cutoff are shorter. So it seems that the problem is within the configuration but it's not a normal behavior.
Maybe I have to let LDOIN and try with external avdd?

0 Luis Fernando Rodriguez S. over 7 years ago in reply to frederic douit

TI__Guru* 84915 points

Hi, Frederic,

Could you try with the external power supplies, please? The audio codec is sensitive to power supplies. This could affect the ADC and DAC behavior directly.

Additionally, have you tried your application in playback mode? I mean, is this problem only related to the ADC or do you have same problems on the playback? Could you try with a bypass mode? You may try it to route the analog input directly to the output.

Best regards,
Luis Fernando Rodríguez S.

0 frederic douit over 7 years ago in reply to Luis Fernando Rodriguez S.

Hello,

Thank you for thoses advises,
I can't do hardware work until monday but I will do it as soon as I can.
When you say in playback mode you mean in DAC mode? I had no problem in DAC mode.
I will try to bypass first to see what happen before applying external supplies.

I saw on an other post that someone fix a similar issue by adding delay (1000 ms), can it be a solution for me? where can I put this delay?

thank you again, I will contact you on monday, have a good week end.

0 Luis Fernando Rodriguez S. over 7 years ago in reply to frederic douit

TI__Guru* 84915 points

Hello, Frederic,

Yes, I would mean the DAC mode. If you don't have any problem with the DAC section and playback mode, I would recommend to try with the loopback modes in the TLV320AIC3204. In that way you may send the ADC data to the DAC input and verify the result in the codec outputs.

Regarding the delay that you mentioned, we only recommend to add delays in several cases:
- After hardware/software reset. The device takes 1ms to get initialized.
- After PLL is powered up. The device requires 10ms to be initialized.

Best regards,
Luis Fernando Rodríguez S.

Hello Louis,

Sorry for the late reply,

I'm not able to do the loopback working :

I put this line w 30 1d 01 after power up dac and adc but I don't get any sound.

What do I miss?

thank you

0 Luis Fernando Rodriguez S. over 7 years ago in reply to frederic douit

TI__Guru* 84915 points

Hi, Frederic,

I think that you are configured the wrong bit. Could you try with the digital loopback (line below)?

w 30 00 00 (page 0 selected)
w 30 1d 10 (D4 - digital loopback)

Best regards,
Luis Fernando Rodríguez S.

0 frederic douit over 7 years ago in reply to Luis Fernando Rodriguez S.

Hi,
Yes, I didn't see that the register settings were on two pages.
But even with the good configured byte I don't get any sound out. I can hear the powering pop but that's all.
I made an other board with an other chip and I have so much less cutoff, it's strange, the only difference is that I use a classic dc-dc converter while the first board use an isolated dc-dc converter. Maybe I have a ground issue, because with the classic converter I grounded with the usb shield, maybe the isolated converter ground is too weak? but no matter for the dac..
I have to test with external supply too.

Hi Louis,

I tried with external supply and unfortunately it's the same behavior...
I'm completely lost at this point.
I don't know where come from the problem.

Any new idea?
thank you

edit: something strange again, if I connect general ground supply (3.3V) with the external ground supply (1.8V) I get very few cutoff. It's definitely a ground issue, but what kind?

0 Luis Fernando Rodriguez S. over 7 years ago in reply to frederic douit

TI__Guru* 84915 points

Hi, Frederic,

Is MICBIAS being connected to GND? In your schematic seems to be connected in that way. MICBIAS is actually a configurable output. So, it may provide a 2.0V, 2.5V or AVDD voltage. Could you try disconnecting this pin? You may leave it floated if it is not in use.

Let me know if the problem persists.

Best regards,
Luis Fernando Rodríguez S.

Hi,
Thank you for your reply.
Sorry, this was a previous design ; current design has micbias left floated, the problem is somewhere else.
