ZHCSDC1D September 2013 – October 2018 TAS5766M , TAS5768M
PRODUCTION DATA.
The TAS576xM supports industry-standard audio data formats, including standard I2S and left-justified. Data formats are selected via Register (Pg0Reg40). All formats require binary 2s-complement, MSB-first audio data, up to 32-bit audio data is accepted.
The TAS576xM also supports right-justified and TDM. I2S, LJ, RJ, and TDM are selected using Register (Pg0Reg40). All formats require binary 2s complement, MSB-first audio data. Up to 32 bits are accepted. Default setting is I2S and 24 bit word length. The I2S slave timing is shown in Figure 35.
