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 single-
port 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.
