In this article, you'll learn how eye patterns are generated and how to analyze eye diagrams for signal integrity by evaluating the eye height, width, jitter, and amplitude. Highlights: An eye diagram is a superimposed view of multiple digital signal cycles, forming an eye-like. An eye diagram is one of the most effective methods for analyzing the signal integrity of your PCB designs. It reveals the quality of high-speed signals by highlighting voltage levels and timing errors. The following is a simplified block diagram of the eye diagram creation process. It then describes different ways that information from an eye diagram can be sliced to gain more insight. Eye diagram are more relevant for wireline communication systems like USB, PCIe.
[pdf] The motor with optical control uses a flat opaque disk with four blades attached to the rotor. If you're interested in the field of robotics and computer vision systems, you've likely heard of optic flow sensors. But what exactly are they, and how are they used. PMW3901 is an optical flow ASIC that computes the flow internally and provides a difference in pixels between each frame. It uses a tracking sensor that is similar to what you would find in a computer mouse, but adapted to work between 80 mm and infinity. It can be used to determine speed when navigating without GNSS — in buildings, underground, or in any other GNSS-denied environment.
