LAN8710Ai-EZK-TR集成電路（IC）的驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

General Description

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 1.2. It is available in both extended commercial and industrial temperature operating versions.

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.
