| Sep 8 at 10:59 | comment | added | Polynomial | @TimWilliams It's a long narrow board with a fairly dense layout, and there will be a dozen of these boards operating in the same environment. I also take pride in the robustness of my designs and would prefer to over-engineer EMI reduction than save a few hours and cents. That said, even if I didn't strictly need synchronised clocks here, the question stands by itself as a matter of good practice. | |
| Sep 8 at 6:50 | comment | added | Tim Williams | Do you know that an EMI issue exists in the first place? Is this a particularly demanding application (say, 20dB+ below commercial levels?), or is layout expected to be too challenging (congested design, narrow board, etc.)? | |
