I started right now to design a board with the ADAU1978.
In the current design, a microcontroller generates all the I2S signals, included master clock.
The question is: can I supply ADAU with all the signals, disable the PLL and not install the PLL fiter? I wasn't able to find an answer on the datasheet or the forums.
Unfortunately, I am very limited in room, so any additional component counts.
