Webinar: A revolução da Ethernet a um par de cabo
The document provides an overview of Single Pair Ethernet (SPE) technology and its standard variations, which utilize a single twisted pair of wires for Ethernet communication, emphasizing its benefits in reducing system costs, weight, and wiring complexity. It outlines various IEEE standards for SPE, including 10base-t1s, 100base-t1, and 1000base-t1, along with applications in automotive and industrial sectors. Additionally, it discusses the specifications, advantages, and product roadmap related to SPE solutions offered by Microchip Technology.
