    A Comment About Commercial ISI Platforms

    Serdes Designer, Characterization folks, I am seeing commercial ISI platforms (the latest one is on sale) that have rather mediocre return-loss (SDD11) in the 1X Nyquist region for 112G PAM4.  Our ISI-112 has almost -30dB of return-loss through 53GHz, with 10dB margin at 67GHz!  This is by far the industry’s best performance. Return loss reflect energy, which [...]

    BER- and COM-Way of Channel-Compliance Evaluation: What are the Sources of Differences?

    In this Signal Integrity Journal article, Vladimir Dmitriev-Zdorov, Cristian Filip, Chuck Ferry, and Alfred P. Neves, CTO of Wild River Technology, analyze the computational procedure specified for Channel Operation Margin (COM) and compare it to traditional statistical eye/BER analysis. There are a number of differences between the two approaches, ranging from how they perform channel [...]
