Hi
I am aiming to create a PCB with 8 Mems microphones. These PDM microphones are then inputted into ADAU7118.

ADAU7118 (Rev. A) (mouser.co.uk)
The reason for using 8 microphones is because the ADAU7118 has 8 inputs, mems microphones are economical and I need to be able to analyse all data streams to determine the direction of audio. Maybe after anylsing all microphones , all 8 might not be nessary.
I need some advice on the PCB layout , some source recommend using a start formation and some recommend a daisy chain, for the CLK and Data traces for each microhones. I have started the PCB layout, buts not finalised i am working out the placemnt and efficient routing to avoid trace via or stubs.
Any reccomendations on PCB layout with multiple Microphones?
