TAS5760M: Questions driving TAS5760 and SW database

Marion Loessl

Part Number: TAS5760M


Hi :)

my customer has some questions regarding TAS5760M:

On the EVM, TAS5760 is driven by AIC3262.

  • Is it possible to drive it by a Microcontroller also? Or is a Codec needed?

another question came up regarding the SW:

  • Is there an example to configure the IC on a SW level as well as on a signal level (driving)?
  • which signal to which timing must be provided? is there an example or a database with function to drive the IC?

Thank you for your help,

kind regards,

Marion

    Hi Marion,

    See my answers below.

    a) Is it possible to drive it by a Microcontroller also? Or is a Codec needed?

    Yes, if the microcontroller can provide I2S signals. See the files below.

    External I2S.cfg

    5751.PPCMB and External I2S_TAS5760XXEVM.pdf

    b) Is there an example to configure the IC on a SW level as well as on a signal level (driving)?

    which signal to which timing must be provided? is there an example or a database with function to drive the IC?

    Take a look at the Section 10.2.1.2 of TAS5760M datasheet. 

    In most cases, you don't even need to initialize TAS5760M via I2C if you can provide 4-wire I2S signals that can be directly accepted by TAS5760M. 

    However, in some other cases (e.g. you want to have the TAS5760M work in the PBTL/Mono mode),  you do need to download some configurations.
