KSZ9031 Gigabit Ethernet Transceivers

Microchip Technology KSZ9031 Gigabit Ethernet Transceivers are completely integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physical layer transceivers for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable. KSZ9031MNX offers the industry-standard GMII/MII (Gigabit Media Independent Interface/Media Independent Interface) for connection to GMII/MII MACs in Gigabit Ethernet Processors and Switches for data transfer at 1000Mbps or 10/100Mbps.
