Brief
Low power and intelligent power management
• Increased active working time
• Prolonged battery life in active standby
• Increased reliability
Improved ease of use and installation, reduced support cost
• Straight-through or crossover cables are accommodated, and such
• Advanced cable diagnostic features to enable remote
• Resistance to cable-sourced electrostatic discharge (CESD) to
DSP-based Signi-PHY™ architecture to ensure performance
over temperature, voltage, and process variation
• Proven in over two billion Fast Ethernet ports
Ease of manufacturing with JTAG support
Fully integrated TX/FX PHY transceiver (MII/RMII-to-TX
magnetics or FX optics)
• Lower system cost
• Simplified system and board design
