TAS5760L Single Speed / Double Speed Mode Select

Jin Kyung Han

Hello

I would like to know the Register Value on the Single Speed / Double Speed Mode Select.

According to the data sheet on 37, The Sampling 32KHz ~ 96KHz are listed only which is Register Value for Single Speed / Double Speed Mode Select.

Let me know the Register Value for 12KHz, 16KHz and 24KHz.

Thanks and Best Regards

Hi, Jin,

The Single Speed / Double Speed Mode Select bit in Digital Control Register is used only to determine if the amplifier will work in single or double speed. The sampling frequencies mentioned in the register table are just few examples of the available sampling frequencies accepted in that mode. The values specified in the table from page 37 are all the supported sampling rates per speed mode:

Single Speed / Double Speed Mode Select Bit:

0 - Single Speed → 12KHz, 16KHz, 24KHz, 32KHz, 38KHz, 44.1KHz, 48KHz.

1 - Double Speed → 88.2KHz, 96KHz.

Best Regards,

1. Master Clock : 6.144MHz
2. L/R : 12KHz
3. SCLK: 384KHz
4. Data: 16bit
