KSZ8091MLXCA

The KSZ8091MLX 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 (UTP) cable.

The KSZ8091MLX is a highly-integrated, compact solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs, by 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.

The KSZ8091MLX offers the Media Independent Interface (MII) for direct connection with MII-compliant Ethernet MAC processors and switches.

Energy Efficient Ethernet (EEE) provides further power saving during idle traffic periods and Wake-on-LAN (WOL) provides a mechanism for the KSZ8091MLX to wake up a system that is in standby power mode.
