The KSZ9131MNXI is an Ethernet Integrated Circuit (IC) from Microchip which provides a Gigabit Ethernet Transceiver with GMII/MII support. It is a single-port gigabit physical layer transceiver device which meets the requirements of the IEEE 802.3, 802.3u, and 802.3ab standards.The KSZ9131MNXI supports both GMII and MII interfaces, allowing customers to integrate it into their designs without having to choose between the two. It also supports advanced features such as low-power usage, IEEE 1588v2 time stamping, reduced cable delay skew, and microprocessor register interface for link status and control. With its technology, it is possible to reduce the burden on the host processor significantly, as the KSZ9131MNXI is capable of handling the packet filtering and time stamping functions autonomously.The KSZ9131MNXI is well suited for many applications including media servers, industrial Ethernet switches, access points, bridge devices, and other related embedded applications that require gigabit Ethernetconnectivity.
