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
- 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 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.
