KSZ8091MNXIA-TR

KSZ8091MNXIA-TR 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 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. The KSZ8091MNX offers the Media Independent Interface (MII). Wake-on-LAN (WOL) provides a mechanism for the KSZ8091 to wake up a system that is in standby power mode. The KSZ8091 provides diagnostic features to facilitate system bring-up and debugging in production testing and in product deployment. Applications include game consoles, IP phones, IP set-top boxes, IP TVs, LOM, printers.
