KSZ8091RNBCA TR

MICREL SEMICONDUCTOR KSZ8091RNBCA TR Ethernet Controller, 100Mbps, IEEE 802.3, 1.8V, 3.3V, QFN, 32Pins

The 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.
