Part Number: TAS5766M

1 TAS5766 IC does not enter the MCLK, only the input of the BCLK/LRCK/DATA  3 signal  I2S is feasible? 
2 TAS5766 IC can automatically identify different Sample rate?
3 TAS5766 IC minDSP at run time, the need to write <I-RAM Block, C-RAM Buffer Block, C-RAM Buffer Block> B, I-RAM Block, C-RAM Buffer A / B are required to change, how to switch?
My initialization process is as follows

    Hi Yu,

    See my comments below:
    1 TAS5766 IC does not enter the MCLK, only the input of the BCLK/LRCK/DATA 3 signal I2S is feasible?
    Andy: Yes. TAS5766 supports 3-wire i2s input.

    2 TAS5766 IC can automatically identify different Sample rate?
    Andy: Yes. If TAS5766 is running SmartAmp processing, the sample rates by PPC3 GUI are only 44.1k and 48k for now.

    3 TAS5766 IC minDSP at run time, the need to write <I-RAM Block, C-RAM Buffer Block, C-RAM Buffer Block> B, I-RAM Block, C-RAM Buffer A / B are required to change, how to switch?
    Andy: Take a look at this app note: www.ti.com/.../slaa425d.pdf.
