PCM510xEVM-U with PCM5142

Other Parts Discussed in Thread: PCM5242, PCM5142, PCM5102, TPA3118D2, TAS5756M, PUREPATH-CMBEVM

Hi TI Experts,

I would like to evaluate the features of mini DSP section of PCM5142/PCM5242. Do I need the original evaluation module  from TI or can I somehow connect the PCM device with PurePath Studio? I guess I need at least this TAS1020 based I2C link, am I right?

From the last project I still have the PCM5102 evaluation board. Can I just replace the PCM5102 with new PCM5142 and use the eval board to play with PCM5142? The eval boards of PCM5102 and PCM5142 look exactly this same.

Cheers,
Tomasz

    Hi Tomasz,

    The EVMs are identical and so you can desolder the PCM5102 and solder on the PCM5142 and have it work correctly.

    Hi Justin,

    Thanks a lot for a quick replay :) Is the TAS1020 firmware this same for different evaluation boards? Can I use this same USB I2C interface for other I2C SW controlled ADC / DAC ICs too?

    Cheers,
    Tomasz

    Hi Tomasz,

    Yes the TAS1020 firmware is common across boards, but later versions of the firmware incorporate newer boards, but all firmware should be backwards compatible.

    Hi Justin,

    Thanks, I just ordered some PCM5142 and I will rework my PCM510xEVM-U.
    I would like to evaluate the PCM5242 too but it doesn’t fit directly on the PCM510xEVM-U board.
    Right now I’m layouting my own PCB for PCM5242 with TPA3118D2.
    Can I use this same TAS1020 interface from my PCM510xEVM-U to communicate PCM5242? Do I just need to connect the I2C interface lines from the PCM510xEVM-U to my PCM5242?
    Beginning of the new year I will also start evaluating the TAS5756M. Can I use, in this same way, TAS1020 section of my PCM510xEVM-U to communicate the TAS5756M too?

    Hi Tomasz,

    Yes the TAS1020 will work to interface with any of our audio parts, as it only enumerates in windows as a USB audio device and will transfer I2S and I2C over USB. The intelligence in what it is sending needs to be coded into the program sending the I2C commands. However the firmware we provide is not meant to be used for comercial use in a product, the TAS1020 is a NRND product so support will be limited.

    Justin,

    thanks for your replay. That is nice, so I can use my eval board for all future tests :) However I thought, the best way is to buy the 'PurePath Console Mother Board for TI Audio Amplifier IC' PUREPATH-CMBEVM just to be sure everything is correctly supported.

    I know the TAS1020 firmware is not for commercial use - I need it just for development and I need in fact just the I2C communication. For the asynchronous USB audio transfer I have my own firmware :)

    Justin,

    one more question, is the TAS1020B firmware in the 'PUREPATH-CMBEVM' and in my 'PCM510xEVM-U' exactly this same?
