KSZ8091MNXIA TR

The 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, 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. It offers the media independent interface (MII) and the KSZ8091RNB offers the reduced media independent interface (RMII) for direct connection with MII/RMII-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 KSZ8091 to wake up a system that is in standby power mode.
