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
