PCB design

Carey Bunks
Hi all,


I'm looking for some help with PCB design.  Specifically, I'd like to collect data from a large number of MEMS microphones mounted on a single board.  The mics are PDM devices that are clocked at about 3mHz, and then downsampled to 16 bit samples at 48kHz.  At 3mHz, I'm concerned that the wires will act like antennas, and interfere with each other.  Can anyone advise on best practice (or provide a reference)?


Cheers,

    I've recently done some signal distribution across 100 devices, but converted to differential pairs for transmission, as this is much more benign than a single-ended signal flapping about. What are your distances between devices & source?
