applications without software configuration
Additional Device Features
Features
Benefits
• High availability using one port for failover
• Higher throughput than single gigabit Ethernet
port
Two complete gigabit Ethernet connections in a single
device
•
Lower latency due to one electrical load on the
bus
• Saves critical board space
• Reduced multi-port gigabit Ethernet costs
Eight activity and link indication outputs that directly • Link and activity indications (10, 100, and 1000
drive LEDs
Mbps) on each port
Internal PLL for clock generation (use either a 25 MHz
crystal or a 25 MHz oscillator)
•
Lower component count and system cost
JTAG (IEEE 1149.1) Test Access Port built in silicon • Simplified testing using boundary scan
On-chip power control circuitry
• Reduced number of on-board power supply
regulators
• Simplified power supply design
Eight software definable pins
• Additional flexibility for LEDs or other low speed
