10/100/100BASE-T SFP/GBIC Module
SUMMARY OF BENEFITS
• _{Simplifies system and board design.}
- Reduced I/O pin requirements with RGMII (over 50%), SGMII
(over 75%), and SerDes (over 80%).
- Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification.
• _{Flexibility for copper or fiber applications.}
• _{Lowers system BOM cost and simplifies system design.}
• _{Provides interoperability with IEEE standard devices operating at 10}
Mbps, 100 Mbps, and 1000 Mbps at half- and full-duplex.
• _{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.
