10/100 BASE-TX PHYSICAL LAYER TRANSCEIVER EEE WOL

The KSZ8081MNX / KSZ8091MNX is a 10Base-T/100Base-TX Physical Layer Transceiver with an MII MAC interface. It utilizes a unique mixed-signal design to extend signaling distance while reducing power consumption, and offers HP Auto MDI/MDI-X for reliable detection of and correction for crossover and straight-through cables, eliminating the need to differentiate between crossover and straight-through cables. The KSZ8091MNX has all the identical rich features of the KSZ8081MNX plus support for Energy Efficient Ethernet (EEE) and Wake-on-LAN (WOL). The KSZ8081MNX / KSZ8091MNX come in a 32-pin, lead-free QFN package and provides an ideal solution for 10Base-T/100Base-TX applications that have tight PCB board space. The KSZ8081MNX and KSZ8091MNX Eval Boards (KSZ8081MNX-EVAL and KSZ8091MNXEVAL) provide a convenient platform to evaluate the features of the device. All configuration pins are accessible either by jumpers, test points or interface connectors.
