Benefits
• Supports back-to-back operation for copper-to-fiber media
converter applications.
• Designed to operate with link partners at all speeds.
• Increased reliability, greater range of power-sensitive
< 275mW (including output driver current) applications.
• Flexible switch/MAC interfacing options. Optimized pin count
interfaces lower cost through reduced trace/simplified routing.
• Operation over the widest variety of cabling plants.
• Automatic detection and correction for straight-through or
crossover cables.
• Reports complete link status.
• Automatically shuts down upon cable removal extending
battery life for mobile applications.
• Easy migration from earlier KS8721B/BT family members.
• Programmable in environments with and without CPU.
• Environmentally friendly and rugged.
• Ideal for space-constrained applications.
