Everybody knows you are supposed to turn off your phone and other electronic devices when you are on a plane. You can leave it on during the flight, but it has to be off for takeoff and landing. I like to remind people in case they “forget”. I tend not to make a big deal during takeoff, but landing has me a little more on edge.
The problem is coupled noise. Sure, most modern planes … Read More
In the lab, both simultaneous switching noise (SSN) and crosstalk look the same. They appear as unwanted pulses of energy that line up with the (aggressor) signal edges. However, the mode of energy coupling is much different between SSN and crosstalk. In the case of crosstalk, they are lining up with the edges because the signal edges are coupling energy onto the victim signal through electric (and … Read More
Crosstalk is everywhere. Really, in a more general sense, noise coupling is everywhere. Usually the method of noise coupling is traditional “crosstalk” – the unwanted transfer of noise from one place to another through coupled electric fields. This most often occurs on PCB designs with dense routing, and on wide parallel busses. Even on newer SERDES busses, however, it is still … Read More
Interconnect loss modeling? Check.
Signal conditioning modeling? Check.
Ability to simulate multiple S-parameter models for things like connectors and packages and vias correctly in the time domain? Oooh…. that’s a tough one. Check!
Ability to include all sources of deterministic and random jitter, worst-case bit patterns, and worst-case crosstalk in the analysis? Wow! Check.
