I have a project that needs to use SDATAIOx of ADAU1467 to expand four I2S inputs. I can't use SDATA_IN0/1/2/3. Because my project has decode board (4 I2S inputs), Bluetooth (1 I2S input), ADC (2 I2S inputs).
According to the datasheet of ADAU1467, SDATA_IN0 (Serial Input Port0) needs to be configured as 4 channels. But the clock combination of SDATA_IN0 is LRCK=48K and BCLK=6.144M, which is not the standard I2S format(LRCK = 48K, BCLK = 3.072M).
So, is there any other way to solve my needs? Thanks！
