    Matt Osborne
    Hi there, I'm attempting to configure the AIC3254 audio interface for recording in master mode (i.e. to generate BCLK and WCLK), and I'm wondering whether I'm missing something... I've read the datasheet and the design guide several times, and I've used this part successfully...

  • Forum Post: Using DSP's in TLV320AIC3254

    Carlos C.
    Hello, We are trying to evaluate the DSP's function in the AIC3254. Question A): We have some doubts in the way to implement interpolation and decimation filter type A (like the ones in processing blocks). How is the method to implement them at Pure Path? we will work at 8Khz. Question B...

    hi, I use MSP430FG4618 to read DC measurement's data of TLV320AIC3254 by SPI, but the data of the registers are't changed. Do you have some code to tell me what steps to set and something to notice? Thanks. p.s. I had opened the analog routiog from IN1L to MICPGA and Headphone...

  • Forum Post: Decimation/Interpolation filters of AIC3254

    Miguel S
    Hi, I have some questions regarding the decimation/interpolation filters: - When a processing block is selected, the corresponding filter (A/B/C) is selected and it is not necessary to do anything else (apart from selecting the right OSR) to configure these filters. Isn't it? - When, instead...

  • Forum Post: Re: Sampling rate of TLV320AIC3204.

    Fangyi Chen
    Hi, J Thanks for the reply. I have further questions in using the audio codec to generate a high frequency tone. 1. Sampling points. Despite the Nyquist, a sine wave may have to have more than 10 sampling point to show its shape. A codec dac is usually limited by its relatively low sampling rate...

    I am having issues getting the AIC3254-CS to recognize the board. It cannot find or update the driver. I have followed the instructions on the included support document. Also I have requested the purepath studio software and still have not received it. thanks Justin

  • Forum Post: Timing Questions about TLV320AIC34

    Bruno Paillard
    We are starting a new project with several TLV320AIC34 on the same McBSP. In this project the relative synchronization of the various channels is important, and I have the following questions: - If several devices (configured as slaves) are cascaded on the same McBSP bus, is it possible for them to use...

  • Forum Post: tlv320aic3254 output inverted

    Michael Norton
    Hello, We are using the tlv320aic3254 in our application at a sample rate of 64 kHz. I've noticed that the output of the codec is inverted with15 bits of range rather than 16 bits. Is this normal? I can provide our register settings if you need them. Thanks.

    Hello. I am experimenting with the TLV320AIC3254 evaluation kit. My target goal is to produce a low power shortwave radio, where most of the processing is done by the 3254. Currently I am having trouble to understand how the ADC processing works. I am confused about which of the processing blocks...

    Hi, We have configured the CODEC and are passing the I2S data corresponding to a 1KHz sinewave. Sampling rate is 96KHz. We are using both internal LDOs so only a +3V3 power rail is used. We are measuring at the CODEC output pin (LOL) with nothing else on that net. When the output is connected to...
