KSZ8081RNAIA TR

MICREL SEMICONDUCTOR  KSZ8081RNAIA TR  芯片, 以太网收发器, 100MBPS, QFN-24

The 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.
