defining a degree of excellence
HIGH SPEED LAN MAGNETICS
960011A
• Designed to enhance performance with National
Semiconductor 10/100 Mbps DSP 83840/83223
chipset
• Split input on transmit channel provides better balance
of differential output signal and greater isolation between
10Base-T and 100Base-TX transceivers
• Cost efficient, multi-port solution
• Compact package fits behind two RJ-45 connectors
• Split design allows common mode chokes to address
10 Mbps or 100 Mbps independent of each other
• Single port options also available, P/N S558-5999-36
and S558-5999-37
• 2000 Vrms isolation
