General Description
The following is list of the general terms used in this document:
The LAN8710/LAN8710i is a low-power 10BASE-T/100BASE-TX physical layer (PHY) transceiver that
transmits and receives on unshielded twisted-pair cable. A typical system application is shown in
Figure
The LAN8710/LAN8710i interfaces to the MAC layer using a variable voltage digital interface via the
standard MII (IEEE 802.3u). Support for RMII makes a reduced pin-count interface available. The
digital interface pins are tolerant to 3.6V.
The LAN8710/LAN8710i implements Auto-Negotiation to automatically determine the best possible
speed and duplex mode of operation. HP Auto-MDIX support allows using a direct connect LAN cable,
or a cross-over path cable.
The LAN8710 referenced throughout this document applies to both the extended commercial
temperature and industrial temperature components. The LAN8710i refers to only the industrial
temperature component.
General Terms and Conventions
