Gigabit Ethernet Front End

Overview

TopologyLAN / POE
IC revisiona

Description

The electronics board has two interfaces, one USB C (USB 3.1) and one Gigabit RJ45/Ethernet interface. The GB-EthernetUSB adapter was developed on the basis of the EVBLAN7800LC Evaluation Board from Microchip. The circuit is built on a 4-layer PCB and in the present design is supplied with voltage via the USB interface. The first part of this Application Note presents the technical basics necessary for understanding the reference design. The second part details the 1 GB Ethernet interface up to the physical layer (PHY in the OSI model). EMC aspects are dealt with in detail in Application Note ANP116.

Features

  • Single Chip SuperSpeed(SS) USB 3.1 Gen 1 to 10/100/1000 Ethernet Controller
  • Integrated Gigabit PHY WITH HP Auto-MDIX
  • Integrated 10/100/1000 Ethernet MAC(Full-Duplex Support)
  • Integrated USB 3.1 Gen 1 SS Device Controller and PHY
  • Low Power Consumption
  • Compliant with Energy Efficient Ethernet IEEE 802.3az
  • Wake on LAN support(WOL)
  • Configuration via One Time Programmable(OTP) Memory
  • Net Detach provides automatic USB attach/detach when Ethernet cable is connected/removed

Typical applications

  • Gigabit Ethernet Front End
