Chalk Talk: Suppressing Noise from Via-to-Via Coupling

Like Cristian Filip who recently spoke on SerDes design, I just did my first Chalk Talk with EE Journal. News editor Amelia Dalton and I talked about how important it is to diagnose via-to-via coupling and how it gets exacerbated due to the PDN (power distribution network) impedance. We also talked about what you can do to suppress that noise. Let me know what you think of our efforts!
