Microchip Physical Layer Transceiver 24-Pin QFN, KSZ8081RNACA

The Microchip KSZ8081RNA/RND 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. 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 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.Single-Chip 10BASE-T/100BASE-TX IEEE 802.3 Compliant Ethernet Transceiver RMII v1.2 Interface Support with a 50 MHz Reference Clock Output to MAC, and an Option to Input a 50 MHz Reference Clock RMII Back-to-Back Mode Support for a 100 Mbps Copper Repeater MDC/MDIO Management Interface for PHY Register Configuration Programmable Interrupt Output LED Outputs for Link and Activity Status Indication
