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.

AC101L FEATURES

• 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 or RMII

• HP Auto-MDIX

• Very small package – 48-pin TQFP

• 49 sq. mm footprint

• Very low power – Typical < 200mW (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/RMII to TX magnetics or FX-Optics)

• Very low system cost

• Simplified board design

• HP Auto-MDIX detects and corrects crossed cables

• Automatically accommodates link partner polarity

• Very 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
