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
