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. Network Tolerance The AC101L includes features that simplify the installation and maintenance of local area networks. One such feature is the HP Auto-MDIX capability, which automatically detects and corrects crossed cables. With HP Auto-MDIX, the installer does not need to know what is on the other end of the network cable; the AC101L automatically switches its transmit and receive circuitry to accommodate the link partner’s polarity. When all system costs are considered, such as power, heat, components and real estate, the AC101L provides the lowest overall system cost and most reliable design. © 2002 by ALTIMA COMMUNICATIONS, INC.
