Geek Speek Webinar – ERL Part 1: What is ERL and How is it Computed?

Presented by: Richard Mellitz Equalization is essential for optimizing channel performance. How can SI engineers account for it? Enter effective return loss (ERL). First introduced in IEEE 802.3cd by Samtec distinguished Engineer Rich Mellitz, ERL provides a figure of merit for signal channels in equalized systems. However, what really is ERL? How can SI engineers leverage this metric? Please join Rich Mellitz as he answers these and related questions in Samtec’s next episode of gEEk spEEk.

“Supply chain.” Who knew that business term would become part of everyday conversation. Supply chain issues are everywhere. Key shipping ports and shipping lanes are finally becoming unclogged. Retailers have too much clothing, but not enough household supplies. Consumers can’t f...
(This is the second in a series of blogs, from Sandeep Sankararaman, Samtec’s Principal RF and Signal Integrity Engineer, discussing design strategies for high-bandwidth RF launches. The first is entitled “What Is An RF Connector Launch?” The third, coming next week, discusses GN...
If you’ve been paying attention to the Coming Soon section in our most recent web updates, you might have noticed we have been working on an upgraded Checkout system for the website for the last several months. We’re happy to announce that this application is now accepting orders...
As signal speeds increase, each part of the signal path getting to and from the device needs to work to higher frequencies.  Strategies that worked in the past no longer suffice and cheaper connectors no longer make the cut. Cable lengths and trace lengths need to get shorter to ...
This month, we released a major new version of our Checkout to a beta state, made some upgrades to how we show lead times online, made 3D model downloads easier from the Search, and released a few more content updates. Here are the major website updates to Samtec.com for July 202...
