  • TLV320AIC3256: Self-boot from EEPROM

    TI Thinks Resolved
    Part Number: TLV320AIC3256 Hi team, Is TLV320AIC3256 able to boot itself by reading EEPROM? And how if possible? Regards, Hayashi

  • RE: TLV320AIC3256: DMIC capture volume is very low

    Hi Vijaya, For Pmic calibration, kindly consult to PMIC vendor. One more thing, can you check whether the audio signal from PMIC is little endian or big endian? Right-justified, left-justified or center? what's the bitwidth of the audio sample and audio…

  • TLV320AIC3256: TLV320AIC3256: Echo Cancellation on External DSP

    TI Thinks Resolved
    Part Number: TLV320AIC3256 Other Parts Discussed in Thread: AM3358 , TLV320AIC3263 Hi Ti Team, I read the previous forum question which states that TLV320AIC3256 can't run Acoustic Echo cancellation (AEC), and It was suggested to use an External DSP for…

  • TLV320AIC3256: TLV320AIC3256: Mono config and Ext Audio amplifier interface

    TI Thinks Resolved
    Part Number: TLV320AIC3256 Other Parts Discussed in Thread: TAS2552 HI TI Team, In one of our Consumer product we are planning to use Audio codec# TLV320AIC3256. Here we have the following queries to be resolved. 1) We require to drive a Mono Speaker…

  • RE: BEAGL-BONE-BLACK: DT changes for am335x-boneblack-common.dtsi for TLV320AIC3256

    Hello Twinkle, By default, our driver does not support the above usecase. If you select McASP as the master and use the internal AUX clock, it will generate the 24MHz signal. Now, it's possible to modify the driver by changing davinci-evm.c file. The…

  • TLV320AIC3256: ADC Data Out?

    TI Thinks Resolved
    Part Number: TLV320AIC3256 I am working with the TLV320AIC3256 both on the evaluation board and on a custom board. We are able to play audio (in both implementations) through the I2S interface, through the headphone and line out ports with no problem…

  • TLV320AIC3256: TLV320AIC326 Temperature change causing MIC_detect issue.

    TI Thinks Resolved
    Part Number: TLV320AIC3256 Hi Team, My customer is running into a problem where MIC_Detect fluctuates without unplugging the MIC when the ambient temperature changes from 25C to -40C and -40C to 25C( they said the problem is easily reproduced when they…

  • TLV320AIC3256: TLV320AIC3256 PPS SW AGC

    Part Number: TLV320AIC3256 Hello, I am currently working to implement AGC on a design using TLV320AIC3256 codec. In my PPS model, Currently I have used the default settings with the SW AGC block. I intend use the following values for my design AGC enabled…

  • TLV320AIC3256: Biquad filter coefficients (derived from sampling rate A) for a different sampling rate B

    TI Thinks Resolved
    Part Number: TLV320AIC3256 Hello, As part of my design, we have 3 biquad filters where the coefficients were calculated based on a 32kHz sampling rate. Is it possible that we could use the same filter coefficients if we cut the sample rate in…

  • TLV320AIC3256: Switching between ADC processing blocks on the TLV320AIC3256

    TI Thinks Resolved
    Part Number: TLV320AIC3256 Hello, I am working on the following design where I have an analog mic and a digital mic interfaced to the codec. I am sampling both the mics at 32kHz. Currently I am making use of the LeftAGC registers to implement AGC for…
