Fixing Signal Integrity Issues in Software?

Fixing Signal Integrity Issues in Software? Yes, you read that right. Unheard of? Read on. The history of electronics is checkered with many things that should have caught on, and others – like the internet – that surprised us with their ubiquity. This post is about something I expected to become one of the greatest boons for Signal Integrity SI : SerDes Equalization Settings SES, only accessible through software . I was wrong. You’d be surprised to learn how many of my custome...

Which Discontinuities are Small Enough to Ignore?

Which Discontinuities are Small Enough to Ignore? A 60 mil via is too small to worry about, right? And that 20 mil solder pad - the signal certainly won’t see that, correct? If you work with high-speed signals, no doubt you’ve asked these questions and someone told you it depends. You might have your own rule-of-thumb RoT that helps you decide which discontinuities – or features – might impact signal quality. In this post I’m going to share my favorite rule-of-thumb...

Understanding Via Impedance

If you routinely give attention to trace impedance but are not accustomed to thinking about via impedance, this post is for you. Or, if you are paying attention to via impedance yet are unsure what dimensions will yield the right impedance, this help with that too. So, when should I use an 8 mil drill? Why should I care? Serial links can fail because of impedance miss-matches discontinuities . In practice, discontinuities are likely causing more problems than loss. While loss degrades a signal s...
