If you've ever attended DesignCon, then there's a good chance you've seen Eric Bogatin's presentations on signal integrity. He usually packs the hall, and with good reason. For one thing, he's been teaching about signal integrity for many years, starting with his own company, Be The Signal, now part of Teledyne LeCroy.
Eric's signal-integrity classes have also become quite popular over the years, but to learn from them, you had to attend in person. No more, for now Eric's classes are available online on an annual subscription basis ($450 individual, $10,000 corporate). At the time of this writing, 48 hours of content are available with another 20 hours on the way, Bogatin told me during a recent conversation.
If you need to get serious about signal integrity, then Bogatin's classes are a good way to start. Indeed, you'll probably want to start with "Essential Principles of Signal Integrity." Videos in this eight-part series run from 1 hour and 45 minutes to 2 hours and 30 minutes. Video sections for this class are:
- The most important SI principles
- Differential pairs
- Reflections and terminations
- Reflections and routing topologies
- Ground bounce
- Signals changing return planes
- Cross talk in uniform transmission lines
- PDN design and EMC control
To get a feel for Bogatin's classes, see the video below from DesignCon 2014. In this excerpt from his presentation, Bogatin covers the most essential principles of signal integrity, starting with what he calls "The poster child for signal-integrity problems," the transmission line.
I asked Bogatin why he decided to put his course presentations online. "I'm traveling less," he said, "in part because I'm now on the faculty at the University of Colorado at Boulder and I need to be here." Now, you don't have to travel to learn from Eric. Although he is traveling less, I'm confident Eric Bogatin will always attend DesignCon.
