The AC101L provides all of the required features of an MII compliant
10/100TX/FX Ethernet transceiver. The AC101L has the lowest power
consumption of any other single- port solution.
With a power dissipation of less than 200 mW, the AC101L is the
industry’s lowest-power Fast Ethernet PHY. The AC101L features an
integrated voltage regulator, and can be supplied by either a 2.5V or 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.
