1.2 General Description
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 inter
face. 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 Section 3.7, "Configuration Straps," on page 29. 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 dis
abled, 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 typ
