The AC101L provides all of the required features of an MII/RMII compliant 10/100TX/FX Ethernet transceiver. The AC101L has the lowest power consumption of any other singleport solution.
With a power dissipation of less than 200 mW, the AC101L is the industry's lowest-power Fast Ethernet PHY. It features an integrated voltage regulator, and can be supplied by either a 2.5V or a 3.3V power source. In addition, the AC101L has several intelligent power-down states that conserve power, yet allow products based on it to automatically turn on when needed. This feature is extremely useful in portable and power sensitive applications such as laptop LAN card adapters. Because most laptop users do not remove their LAN PC cards when working remotely, this feature results in a noticeably extended battery life for laptop computers.
