MICROCHIP LAN8820I-ABZJ Ethernet Controller, Ethernet PHY Transceiver, IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, 1.14 V

The LAN8820I-ABZJ is a RGMII 10/100/1000 Ethernet Transceiver with HP Auto-MDIX support. It is fully compliant with the IEEE 802.3 and 802.3ab standards. It can be configured to communicate with an Ethernet MAC via the standard RGMII interface. It contains a full-duplex transceiver for 1000Mbps operation on four pairs of category 5 or better balanced twisted pair cable. Per IEEE 802.3-2005 standards, all digital interface pins are tolerant to 3.6V. It is configurable via hardware and software, supporting both IEEE 802.3-2005 compliant and vendor-specific register functions via SMI. It implements AutoNegotiation to automatically determine the best possible speed and duplex mode of operation. HP Auto-MDIX support allows the use of direct connect or cross-over cables.
