TAS5766M: Question of TAS5766 SDOUT Leakage

Part Number: TAS5766M


Hi Sirs,

Please refer to the scope waveforms, the TAS5766's SDOUT keeps the its latest status as BCLK off, it makes leakage problem in suspend mode (D3/S3/S4/S5). 



This problem could be fixed by sending "w 98 08 00" before entering suspend mode and "w 98 08 20" after resume to normal operation (S0/S3). However, do we have better suggestion to bring SDOUT to logic low when BCLK off without write any parameters?

Thank you and Best regards,

Wayne Chen
