10/100BASE-TX SINGLE-CHANNEL TRANSCEIVER
FEATURES
•
10BASE-T/100BASE-TX/100BASE-EFX IEEE 802.3u fast
Ethernet transceiver
SUMMARY OF BENEFITS
•
DSP-based architecture to ensure performance over
temperature, voltage and process variation.
- Field proven in over one billion Fast Ethernet ports.
- Superior ability to link and lower BER in marginal cable
plants, relative to analog solutions.
- Greater ATE coverage results in fewer field failures.
Improved ease of use and installation, reduced support cost.
- Straight-through or cross-over cables accommodated
independent of installation.
- Advanced cable diagnostic features to enable remote
monitoring and debug of cabling infrastructure.
- Resistance to CESD to reduce product destruction and
product returns.
Flexible power supply options.
Low power and intelligent power management.
- Increased active working time.
- Prolonged battery life in active standby.
- Increased reliability.
Control of network interaction on start up.
