LAN8830-V/PSA

The LAN8830 is a completely integrated triple-speed (10BASE-T/100BASE-TX/1000BASE-T) Ethernet physical-layer transceiver for transmission and reception of data on standard CAT-5 as well as CAT-5e and CAT-6 unshielded twisted pair (UTP) cables. The LAN8830 provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to RGMII MACs in Gigabit Ethernet processors and switches for data transfer at 10/100/1000 Mbps. The LAN8830 reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential pairs and by integrating an LDO controller to drive a low-cost MOSFET to supply the core voltage.
