KSZ8081RNAIA-TR

KSZ8081RNAIA-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 KSZ8081RNA is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs and by integrating a low-noise regulator to supply the 1.2V core and by offering 1.8/2.5/3.3V digital I/O interface support. The KSZ8081RNA offers the Reduced Media Independent Interface (RMII) for direct connection to RMII-compliant MACs in Ethernet processors and switches. Typical applications include game consoles, IP phones, IP set-top boxes, IP TVs, LOM, printers.
