TAS5825M: SCLK and LRCLK input at start up sequence of TAS5825M

Part Number: TAS5825M


Hi 

My customer is asking if it is possible to set DSP Coeff. By inputting SCLK instead of inputting SCLK and LRCLK at the same time as specified in the datasheet in the TAS5825M Start up sequece.

In actual testing, only the SCLK is input and the DSP Coeff. After setting, I found out that if you enter LRCLK later, the value of DSP Book 0xaa is changed.

I think it is necessary to enter both SCLK and LRCLK together, but the customer wants to check whether the initial start-up sequence is possible with SCLK only.

1. Is there a way to supply the DSP coeff. Setting without the above problem by supplying only SCLK?

2. SCLK and LRCLK are the DSP coeff. Can you give an overview of how this works in configuration?

Pleas check it.

Thank you.

Best regards.

From Anthony.
