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.

FETURES

• Single port—10BASE-T/100BASE-TX/100BASE-FX, full duplex or half-duplex

• Power supply: 2.5V or 3.3V

• Integrated voltage regulator to allow operation from single supply source

• Single port—MII

• HP auto-MDIX

• Small package—48-pin TQFP, 49 square mm footprint

• Low power—typical less than 200 mW (100BASE-TX)

• Fully compliant with IEEE 802.3/802.3u

• Baseline wander correction

• Multi-function programmable LED outputs

• Reverse polarity detection and correction

• Read/write register bit indication

• Industrial temperature (3.3V only)

SUMMARY OF BENEFITS

• Fully integrated TX/FX PHY transceiver (MII to TX magnetics or FX-Optics)

• Low system cost

• Simplified board design

• HP auto-MDIX detects and corrects crossed cables

• Automatically accommodates link partner polarity

• Small footprint to allow reduced real estate in space-critical applications such as PCMCIA cards

• Industry’s lowest power Fast Ethernet PHY

• Accommodates either a 3.3V or a 2.5V power supply

• Low-power and intelligent power management

• Standby mode to conserve power
