KSZ8081RNAIA TR Datasheet PDF - Micrel

The KSZ8081RNAIA TR is a Physical Layer Transceiver with RMII support and a single-supply 10Base-T/100Base-TX Ethernet for transmission and reception of data over standard CAT-5 unshielded twisted pair cable. It 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. It offers the media independent interface for direct connection with MII-compliant Ethernet MAC processors and switches.

● Back-to-back mode support for 100Mbps copper repeater

● MCD/MDIO management interface for PHY register configuration

● Programmable interrupt output

● LED outputs for link, activity and speed status indication

● On-chip termination resistors for the differential pairs

● Power-down and power-saving modes
