AC101L provides required features MII/RMII compliant 10/100TX/FX Ethernet transceiver. AC101L lowest power consumption other singleport solution. With power dissipation less than AC101L industry's lowest-power Fast Ethernet PHY. features integrated voltage regulator, supplied either 2.5V 3.3V power source. addition, AC101L several intelligent power-down states that conserve power, allow products based automatically turn when needed. This feature extremely useful portable power sensitive applications such laptop card adapters. Because most laptop users remove their cards when working remotely, this feature results noticeably extended battery life laptop computers.
Network Tolerance AC101L includes features that simplify installation maintenance local area networks. such feature Auto-MDIX capability, which automatically detects corrects crossed cables. With Auto-MDIX, installer does need know what other network cable; AC101L automatically switches transmit receive circuitry accommodate link partner's polarity. When system costs considered, such power, heat, components real estate, AC101L provides lowest overall system cost most reliable design.
