This file type includes high-resolution graphics and schematics when applicable. High-speed serial interfaces are the primary I/O architecture of most of today’s communications products. Virtually all ...
Analyzing closed eye diagrams is tricky. The primary eye-closing culprit is inter-symbol interference ISI), which is caused by the frequency response of the channel. I’ve written about closed eye ...
This rule of thumb enables us to estimate how much attenuation would be in the loss budget of a serial channel. Spoiler summary:With no equalization, about -10 dB at the Nyquist. With just CTLE, about ...
As high-speed serial data rates advance beyond 50 Gb/s, conventional logic-emulating non-return-to-zero (NRZ) signaling is being replaced by PAM4, a four-level pulse amplitude-modulation scheme. PAM4 ...
The relentless demand for massive amounts of data is accelerating the pace of high-performance computing (HPC) within the high-speed Ethernet realm. This escalation, in turn, intensified the ...
The paper explores the challenges facing designers implementing systems that are compliant to 10GBASE-KR and CEI11-LR standards. These systems can be 40-50†with multiple connectors and it is ...
