Simplifies system and board design.
- Reduced I/O pin requirements with RGMII (over 50%).
- Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification.
•
Provides interoperability with IEEE standard devices operating at 10,
100, and 1000 Mbps at half- and full-duplex.
•
Lowers system BOM cost and simplifies system design.
•
Requires no airflow or heatsink.
•
Provides compliance with PCI 2.2 and PC99/PC2000.
•
Eases system level debug.
•
Reduces system design constraints to meet EMI emissions standards.
•
Cable diagnostic function characterizes cable plant condition and
immediately indicates cabling issues.
- Prevents erroneous equipment return due to bad cable plants.
- Prevents manufacturing fall-out due to bad cable plants.
•
High 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.
