Hi Andre,
Welcome to E2E, thanks for your interest in our products!
You can find the gerber files for the PCM5242RHBEVM in the product folder in TI.com.
Unfortunately we don't have an available Linux driver for this device, i will suggest you to surf in the web and see if you have any luck to find it on any open sources webpage.

Hello Andre,
The only available information about the TPA3251D2 is the one that is in the product folder in ti.com.

Dear Diego
thank you for your support.
do you know if any samples are available or when more info will be released?
thanks
Andre
Dear Diego
can you tell me where we can find a reference design for this chipset TPA3251D2 ?
i have looked through the documents available online, but nothing.
thank you for your support.

Hi Andre,
question about linux drivers is not relevant, because PCM5242 use standard DAC I2S bus. For Linux or any other operating system you need some hardware which convert audio data from a computer or device to I2S bus.
1. You can use S/PDIF receiver like chip DIR9001 which convert S/PDIF output from a device to I2S bus. It works up to 92kHz/24bit.
2. You can use USB to I2S converter. TI has simple chip PCM2706C which support UAC1 mode and works up to 48kHz. It works without any drivers under Linux, MacOS X or Windows XP and up. Volume doesn't work for I2S output.
3. You can build USB to I2S convertor with support up to 192kHz or 384kHz on some DSP chip. TI recommended TMS320C5533 because TAS1020 is not produced anymore. There also exists USB-I2S convertors based od XMOS or Atmel chips with a free firmware implementation of UAC2 mode. With your own firmware you can implement Volume, Mute or other mixer functions what do you want.
Linux and MacOS X support UAC2 (USB Audio Class 2) mode natively, but for Windows you need UAC2 audio driver. There also exist free implementation of this driver.

some work has been done on a PCM5122 driver, which is reg map compatible with the PCM5242.
However, it belongs in the open source community and was created by an organization outside of TI.
e.g. github.com/.../codecs
Pavel, your comment regarding simply treating it as a I2S device fits perfectly for devices like the PCM5102 that have no I2C/SPI interface. Sadly, for I2C devices, we like to open some of the easter eggs in parts enabled by the I2C :)
