TAS5754 in master mode generating sclk and lrclk

Abel Bergeron

Hello,

I am trying to output the sclk and lrclk from the TAS5754 in master mode. The only clock i'm feeding is the mclk on pin 22. I have follow the instruction of the user manual to set the appropriate register and I'm writing the value in the register via I2C.

The thing is I don't have anything on the pin 25 and 23 (lrclk and slck output) after the register set up. The mlck I use is 24.57 Mhz and I need fs of 48Khz.

Does anybody have the value of all the register needed to make this work?

Thanks

Hi Abel,

What are the register settings you are trying now? I can double check using my hardware.

Thanks for offering your help. I found the solution not long after posting. I forgot to reenable the SLCK and LRCLK divider after the reset. This is done by setting the 2 LSB of the register 12 (0x0c) in case anyone have a similar problem.
