Hi Expert,

If I don't have MCLK for TAS5731M, but the BCLK could be 3.072MHz. Can I connect MCLK and BCLK together? Thanks!

Hi, Jerry,

The TAS5731M, and all the TAS57xx family of amplifiers require a MCLK signal for a correct operation. For most TAS57xx devices, 44.1/48 KHz mode allows the use of a 64×Fs MCLK rate. This rate also happens to be one of the supported SCLK rates. So, SCLK can be connected with MCLK as long as the sampling rate is 44.1/48 KHz and the frequency of MCLK/SCLK is 64×Fs.

You can find the available clock combination of the TAS57xx family in the following Wiki page:
