Other Parts Discussed in Thread: TAS2552

Hi relevant guys

Could you let me know the possibility to change the PWM output frequency from 300kHz(±25Hz)?

  • The reason is to conflict with Wacom solution.
  • Currently Samsung is looking for the other solutions have different output frequency
  • The target module is next gen. flagship tablet module will have 4 speakers and target MP is around early 1Q 2015.

Thanks and Best Regards

    Hi, Billy,

    that is hard coded into the chip, so in order to change it, would require a new device to be made. 

    if you want to pursue this, please check with Murugavel on the business case. 

    You might also check tas2552, I don't remember if the freq is programmable on it.
