LAN8810

The Microchip LAN8810/LAN8810i is a low-power 10BASE-T/100BASE-TX/1000BASE-T Gigabit Ethernet physical layer (PHY) transceiver with variable I/O voltage that is fully compliant with the IEEE 802.3 and 802.3ab standards.

The LAN8810/LAN8810i can be configured to communicate with an Ethernet MAC via the standard MII (IEEE 802.3u)/GMII(IEEE 802.3z) interfaces. 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.

The LAN8810/LAN8810i is configurable via hardware and software, supporting both IEEE 802.3-2005 compliant and vendor-specific register functions via SMI. The LAN8810/LAN8810i implements Auto-Negotiation 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.
