How much common-mode noise is too much? Join Rich Mellitz and Istvan Novak as they wrestle with this question. This gEEk spEEk discussion covers why we should be concerned with common mode noise over wide frequency ranges, with a special focus on how power distribution and signaling networks impact receiver performance. What can board/system designers do to mitigate this noise? How can it be tested, measured, and modeled? Join this session to learn how you can perform simulations and measurements to evaluate your design's sensitivity to common mode noise. Topics covered include: measurement experiments, modeling, and specifications.
