The Microchip KSZ8091 series is a single-supply 10Base-T/100Base-TX Ethernet physical-layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair cable. The KSZ8091 is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs, integrating a low-noise regulator to supply the 1.2V core and by offering a flexible 1.8/2.5/3.3V digital I/O interface.

Single-chip 10Base-T/100Base-TX IEEE 802.3 compliant Ethernet transceiver
Wake-on-LAN support with either magic packet, link status change, or robust custom-packet detection
Power-down and power-saving modes
Built-in 1.2V regulator for core
On-chip termination resistors for the differential pairs
