TAS2560: Initialization Code from datasheet vs GUI generated code

Kelvin Tee

Part Number: TAS2560


Hi 

My customer has designed TAS2560 on the audio set and they found discrepancy between the init code from datasheet vs the code generated from the EVM GUI.

Could you explain the function of the code highlighted in "red" in the excel sheet. Customer found strange behavior when using the code downloaded from the GUI.Initial Data TAS2560 EVM.xlsx

    Hi Kelvin,

    What is the strange behavior? Some kind of noise or no audio?
    Have you also tried to write the values obtained from GUI on cfg format? Is the behavior different between using cfg and h files?

    Hi Ivan

    Abnormal sound was observed. TAS2560 become hot even with no audio playback.
    Customer had tried both format with the same outcome as above.

    Kelvin,

    Are you using the EVM? If not, could you share schematic and overall system characteristics, like clock and sampling frequencies, load impedance.
    If you're using the EVM, can you send the cfg file so I can try to recreate this in the lab?

    It is working on customer prototype PCB. It they remove the the GUI generated code with "META..." (please refer to my earlier attachment), TAS2560 is working fine.

    Sampling Rate: 44.1kHz

    Clock: 11.2896MHz

    Load: 4Ohm

    Kelvin,

    Based on this I would recommend to keep removing the "META" content from GUI generated code.
    I'll follow up on this and try to replicate it in the lab. So far I'm not able to get the device to heat on the EVM.
    If I get a similar situation then I'll drive the necessary changes to the GUI.
