Hi, I need some advice. I have a tuner to which I need to connect a BT I2S receiver.
Contains SRC AD1895 which is set MMODE select 0 0 0 Both Serial Ports Are in Slave Mode and 16bit length. Ports MCLK in and MCLK out is set 11.2896Mhz. I can't change the MCLK.
I2S bus LDAC bluetooth receiver provides LRCLK 96khz and 24bit length.
Setings pins SRC AD1895 MMODE - Output Serial Port Is Master with 256 × fS_OUT. Will there be downsampling from 96kHz to 44.1kHz and change from 24bit to 16bit if the MCLK is 11.2896MHz?
I need to get I2S only 16 bit long and 44.1kHz because the following circuit can't handle anything else and can't be changed in any way.
Thank you very much for your help

https://www.analog.com/media/en/technical-documentation/data-sheets/AD1895.pdf end of page 19: "The master clock has to be at least 138 times greater than the maximum input or output sample rate." 138 * 96 kHz = 13.248 MHz > 11.2896 MHz, so it should not work.
