Hi!
When I was using the ADAU1787, I employed the TDM mode of I2S and found that the maximum speed of BCLK was 24.576 MHz, and the sampling rate for 16 channels was 192K. However, my application scenario required an 8-channel TDM transmission at a sampling rate of 192K. Therefore, BCLK needed to be 49.152K. But SigmaStudio did not allow me to do this.

If it is not possible to do so, then could you please tell me what methods I can use to achieve a 49.152 MHz transmission for the output BCLK?
The control word of register SPT0_BCLK_SRC, I guess, is a coefficient control word for a PLL. When it is set to 100, it operates at 24.576 MHz. If it is set to 101, can it then work at 49.152 MHz?
Looking forward to your reply! Thank you very much! Wish you a good mood!
