KSZ9021RLI, Ethernet ICs GbE Physical Layer Transceiver with RGMII

Semiconductors\Communication & Networking ICs\Ethernet ICsKSZ9021 Gigabit Ethernet TransceiverMicrochip Technology KSZ9021 Gigabit Ethernet Transceiver is a completely integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ9021 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 1.2V core.
