TAS2505: TAS2505 drvier

Hi Luis;

Tas2505 according to the following settings, the output 9&12pin  can test 288KHZ PWM signal, but there is no sound. According to this settings, what frequency does the input MCLK BCLK WCLK need? Are there any good suggestions?18 pin  not connet to mcu

Hi, 

I would recommend the following clock values:

MCLK = 11.2896 MHz
BCLK = 2.8224 MHz
WCLK = 44.1KHz

Please let me know if you have additional questions or comments.

Best regards,
