How to drive a clock signal to 20 digital microphone. The clock is generated from FPGA and about 3MHz frequency. First mic's line 2cm and last one's 15cm away from FPGA clock out pin. Also all mics should be sync.
- FPGA drive strength could adjustable, but can it still drive 20 mics at this distance?
- I found some clock driver, fanout buffer and similar ICs. Can someone who has experience give me an IC recommendation? Also if i need, how to locate it in PCB?
