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,

Carey

Thanks for your response, Alex. Yes I should have written MHz (3e6). To answer your question, this project will use roughly 100 microphones. Do you have experience with MEMS mics?
