Low-power, quad-port integration enables single-row, high-port-
density switches.
Provides compatibility with IEEE standard devices operating at 10,
100, and 1000 Mbps at half-duplex and full-duplex.
Lowers system BOM cost and simplifies system design.
Ethernet@Wirespeed controls auto-negotiation advertising to enable
link establishment at lower speeds when a 1000BASE link fails to be
established.
Enables use of low-cost magnetics, even in high-density (48+ port)
designs.
Eases system level debugging.
CableChecker software characterizes cable plant condition and
immediately indicates cabling issues.
Over 3 kV of CESD tolerance prevents equipment damage and
return.
Operates with larger packets for wider range of packet protocol
support and improved efficiency.
Ease of manufacturing with JTAG support, simplified power supply,
and multiple MAC interfaces.
