TLV320ADC3100: Is the official website driver available?

XIANG HUANG

Part Number: TLV320ADC3100

Our company uses this IC for recording. We downloaded the driver from the official website, and the register configuration is as follows, but the recording failed. Is there a problem with register configuration?

Hello, what operating system do you use, Linux or Android? Do you have any screenshot of the failed information?

linux4.4 buildroot

dowload driver path:

https://git.ti.com/cgit/ti-analog-linux-kernel/dmurphy-analog/tree/sound/soc/codecs/tlv320adc310x.c?h=tlv320adc310x_318&id=9ade84cc7e746abbf6bd9c12051eba3b80f056a9

I found that the downloaded header file is completely not on the Datasheet, such as the address of page1 and so on.

HI

Is there a new driver?

Hello, how to configure the MCLK of this chip? I can't get the MCLK signal from my side

Sorry to reply you so late, and I didn't find the ADC3100 Linux driver of Verison4.4. We have the TLV320ADCx140 linux driver which is similar with ADC3100. By the way, this driver is meant to run with Linux v5.x. The Linux ALSA drivers changed somewhere around v4.x and these drivers are not compatible with earlier versions. In addition it need to replace all the register commands from the TLV320ADCx140 with the corresponding commands of the TLV320ADC3100.

Here is the link for the TLV320ADCx140 linux driver.

The device tree binding example is at:

git.ti.com/gitweb

The documentation with the example at the end of the document to setup the I2C is at:

https://git.ti.com/gitweb?p=ti-analog-linux-kernel/dmurphy-analog.git;a=blob;f=Documentation/devicetree/bindings/sound/tlv320adcx140.yaml;h=1433ff62b14f0264ae5278d40a612da8a82ad718;hb=47d53a01e1835c56eec2f301b93156c494f3e068

Can the I2S MCLK of this chip be provided by itself or can only be provided by CPU and can only be done in slave mode

0 Kailyn Chen 2 年多前回复 XIANG HUANG

TI__Guru**** 295050 points

Hello,

If you don't connect external MCLK input, the BCK input on ADC3100 can be used as the PLL input to generate the required internal MCLK.

Please see section 8.3.6 Audio Clock Generation in the datasheet.

Could you please tell me whether TLV is the master or CPU is the master? I need to configure CPU

0 Kailyn Chen 2 年多前回复 XIANG HUANG

TI__Guru**** 295050 points

If you used the BCLK as PLL input to generate the internal MCLK, the TLV is the slave mode, because if the TLV is master, the BCLK is an output.

I am now sending MCLK from the CPU side to the TLV. I use oscilloscope to measure TLV pin (MCLK, LRCK, SCLK, SDI0) are normal, ARecord-d hw:0,0 --period-size=1024 --buffer-size= 4096-r 48000-c 2-f s16_le R.av Is the register not matched?

The data I have recorded now is some noise. I think there is something wrong with the output of the chip's SDI0. May I ask if there is something wrong with the configuration of the register?

Hello, if there is some noise, it should not to be related to the register configuration, please refer to the FAQ about the " Audio CODECs and ADCs: Common Noise Issues":
