Microchip Technology KSZ8563R 3-Port 10/100 Ethernet Switches
Microchip Technology KSZ8563R 3-Port 10/100 Ethernet Switches are a highly-integrated, IEEE 802.3 compliant networking device that incorporates a layer-2+ managed high-performance Ethernet switch, two 10BASE-T/100BASE-TX physical layer transceivers (PHYs) and associated MAC units. Additionally, one MAC port with a configurable RGMII/MII/RMII interface for direct connection to a host processor/controller, and another Ethernet switch, or an Ethernet PHY transceiver.
The Microchip KSZ8563R 3-Port 10/100 Ethernet Switches are built upon innovative Ethernet technology, with features designed to offload host processing and streamline the overall design. The KSZ8563R is offered in industrial (-40°C to +85°C) and extended (-40°C to +105°C) temperature ranges.
