General Description
The following is list of the general terms used throughout this document:
The LAN8710A/LAN8710Ai is a low-power 10BASE-T/100BASE-TX physical layer (PHY) transceiver
with variable I/O voltage that is compliant with the IEEE 802.3-2005 standards.
The LAN8710A/LAN8710Ai supports communication with an Ethernet MAC via a standard MII (IEEE
802.3u)/RMII interface. It contains a full-duplex 10-BASE-T/100BASE-TX transceiver and supports
10Mbps (10BASE-T) and 100Mbps (100BASE-TX) operation. The LAN8710A/LAN8710Ai 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 LAN cables.
The LAN8710A/LAN8710Ai supports both IEEE 802.3-2005 compliant and vendor-specific register
functions. However, no register access is required for operation. The initial configuration may be
selected via the configuration pins as described in
Register-selectable configuration options may be used to further define the functionality of the
transceiver.
Per IEEE 802.3-2005 standards, all digital interface pins are tolerant to 3.6V. The device can be
configured to operate on a single 3.3V supply utilizing an integrated 3.3V to 1.2V linear regulator. The
linear regulator may be optionally disabled, allowing usage of a high efficiency external regulator for
lower system power dissipation.
The LAN8710A/LAN8710Ai is available in both extended commercial and industrial temperature range
versions. A typical system application is shown in
