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 at half-duplex and full-duplex.
Requires no airflow or heatsink.
Lowers system BOM cost and simplifies system design.
Eases system-level debug.
Enables use of low-cost magnetics, even in high-density (48+)
designs.
Cable diagnostic function characterizes cable plant condition and
immediately indicates cabling issues.
Over 4 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.
- Lowers system costs by eliminating PCB layers required for
- Reduced I/O pin requirements with RGMII (over 50%),
- Clock timing can be adjusted to eliminate board trace delays
- Lowers MAC/switch costs by reducing the number of pins
- Prevents erroneous equipment return due to bad cable plants.
- Prevents manufacturing fall-out due to bad cable plants.
