Microchip Ethernet Bridges

Ethernet Bridges

Ethernet bridge devices enable you to implement Ethernet connectivity to a host processor via USB, High-Speed Inter-Chip (HSIC), Peripheral Component Interconnect (PCI™) or PCI Express® (PCIe®) interfaces. In the case of USB, these solutions enable fanning out the local bus, providing flexibility towards additional downstream ports.

PCIe to Ethernet

Fully integrated stand-alone 10/100/1000 Mbps networking solutions

MII/RGMII interface for flexible integration

Harness power advantages within the PCIe 3.1 specification for a modern design approach

Single supply, single clock or crystal

USB to Ethernet Hub Combo

Fully-integrated 2/3/4-port Hi-Speed USB 2.0 hub and 10/100 Ethernet controllers

UniClock technology uses a single 25 MHz crystal for both USB and Ethernet connectivity to simplify the clocking scheme, eliminates the need for extra components when adding USB hubs and reduce system BOM cost

Support for multiple operating systems including Windows® 7, Windows XP, Windows Vista, Windows CE, Windows Mobile, Linux® and macOS®, among others

Industrial temperature range (-40° to 85°C) options available

Standalone USB to Ethernet

Single-chip, Hi-Speed USB 2.0/HSIC to 10/100 and 10/100/1000 Ethernet controllers

Requires only a single 25 MHz crystal

EEPROM-less design option helps to reduce BOM costs

Implements reduced power operating modes including enhanced energy detect power-down

Supports numerous power management features including Wake-On LAN, Magic Packet™ and Link Status Change

External MII and Turbo MII (available for speeds up to 200 Mbps)

Industrial temperature range (-40° to 85°C) options available
