TAS5805M: The chip is not powered on during playback

Hi Kai,

            1. What's the clock of 24.576MHz? What's your audio format, TDM or I2S? Pls share your I2S signal waveform.

            2. What's the value of Register 0x71 in book0 page0 when read back?

Leon

Hi Leon ,

My format :

use TDM to playback

sample 48kHz  , slot : 32 , bit_width : 16bit

0x71 = 0x04

Hi Kai,

           From you register reading:

           0x33= 0x10  (TDM, 16bit width)

           0x34=0x01  (One BCK shift)

          Looks your configuration is good. But one concern need your confirm:

         1. What's your LRCLK signal? It's just one bit or 50% duty cycle? If one pulse you need set 0x33 as 0x14

Leon

Hi Leon,

I agree with your idea, my FS signal is short sync, which is less than 8sclk

My FS/CLK signal is as follows:

Hi Leon,

I want to play music through SDIN and output the music being played from DOUT at the same time, which means I want to get the recovery data, which register do I need to configure?

I check the datasheet, 0x03 = 0x01,I use an oscilloscope to measure the waveform, the output waveform is different from the input 

0x30h

SDOUT Select. This bit selects what is being output as  SDOUT pin.
0: SDOUT is the DSP output (post-processing)
1: SDOUT is the DSP input (pre-processing

Hi Leon,

Can tas5805m receive the falling edge trigger ？ The FS of my current platform is the falling edge short sync ，the register support does not support this configuration ？

FS wav of my platform as bellow show
