TAS2110: TDM clock error

Amy Luo

Part Number: TAS2110

Hi team,

Connect TAS2110 with I2S, the sampling frequency of I2S is 16KHZ, the ratio of SBCLK and FSYNC is 64, the frequency of FSYNC is 16KHZ, and the frequency of SBCLK is 1024kHZ. （The value of TDM_DET register is 0x21).

But the value of INT_LTCH0 register(Page0 0x24) is 0x4, "interrupt due to TDM clock error"

(since PWR_CTL will be set to 0xe automatically after TDM clock error, I changed the value of INT_CLK to 0x45, so the value that can be seen in PWR register is 0xc.)

Attached is the register list, please help to see if there is any problem with the TAS2110 configuration.

Hi,

Are you making progress?

Hi Amy,

I would recommend to get the device configuration script from PPC3 using End System Integration. Here you can select the Sample Rate you're using.

Could you please share a capture of your SBCLK and FSYNC signals? Your 16kHz and ratio of 64 should be supported by the device.
Are you using the EVM or a custom system?

Hi Ivan,

The customer didn't purchase EVM board, they used their own design board, and they didn't use PPC3. The figure shows the signal of SBCLK and FSYNC

Hi Amy,

I'll send a test report using the same SBCLK and FSYNC as customer application, perhaps having the same procedure as we do they can make progress on their testing. I'll send the report by tomorrow evening.

If you consider necessary, we can also sync offline for webex debug session, just let me know.

Hi Amy,

Could you please ask customer to only send the power up command to the device on their system, instead of the full initialization script? This is writing 0x0c into register 0x02, I think the device should work OK with default register values and their sampling frequency.

In addition, is it possible to have a capture of the FSYNC and SBCLK clocks along with initialization commands? The clocks should be present before the device comes out of shutdown mode, otherwise it will detect TDM clock error.

Hi Ivan,

After the customer tests, it is found that as long as the value of 0x06 register is changed, the problem of "TDM clock error" will appear.

Because the customer needs 16K sampling rate, but the default is 48K, so TDM_ CFG0 (0x06) register needs to be configured as 0x43.

So what might be the problem?

0 Ivan Salazar over 4 years ago in reply to Amy Luo

TI__Guru** 109545 points

Hi Amy,

Do you know if the audio is OK if they don't change the value of register 0x06?

Also, I think they shared a register dump, but can they share the script they use to configure the device? I'd like to check if the device is in shutdown mode while the registers are being modified. The power up command (register 0x02) should be the last one in the script.

Hi Amy,

It's been a week since last communication (possibly due to holidays), we'll wait up to the end of the week for any further updates you could share. Thanks.

The customer stated that after writing the register 0x02 to 0xc, it will soon become 0xe. It is not clear why. What would be the possible reason

0 Ivan Salazar over 4 years ago in reply to Amy Luo

TI__Guru** 109545 points

Hi Amy,

From previous description I think TDM clock error has been triggered, is it still happening? The device would go to software shutdown if an error is triggered.

Also it was mentioned that if register 0x06 was modified, error happens, if they don't write into register 0x06 is it working OK?

Hi Ivan,

According to your guidance, the problem has been solved. Thank you very much for your continuous support during this period.

The clocks should be present before the device comes out of shutdown mode, otherwise it will detect TDM clock error.
