SUMMARY OF BENEFITS
•
Low-power, quad-port integration enables single-row, high-port-
density switches.
- Lowers system costs by eliminating PCB layers required for
routing high-density solutions.
- Reduces I/O pin requirements with RGMII (over 50%), SGMII
(over 75%), and SerDes (over 80%).
- Supports clock timing adjustment to eliminate board trace delays
required by the RGMII specification.
-
Lowers MAC/switch costs by reducing the number of pins
required to interface with the PHY
.
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.
- P
revents erroneous equipment return due to bad cable plants.
- Prevents manufacturing fallout due to bad cable plants.
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.
