The cure for sick waveforms

The cure for sick waveforms

Found a signal integrity problem in the lab?  How do you go about fixing it?  Well, if it’s a SERDES…

Running at 6GHz with your eyes closed can be scary

Running at 6GHz with your eyes closed can be scary

Running at 6GHz is actually kind of scary regardless, but especially so with your eyes closed.  And I mean that…

It’s never too late

It’s never too late to fix a design problem.  Well, maybe if the product is shipping, that might be classified…

Try to fit some plane pairs in your stackup

Try to fit some plane pairs in your stackup

At the very minimum, a good board stackup has solid reference planes for signal routing.  Power demands now pretty much…

Stackups: More than just a bunch of routing layers

Stackups: More than just a bunch of routing layers

Proper stackup design is the key to ensuring maximum performance for your PCB design.  Electromagnetic compatibility, signal integrity, power integrity…
